Venus, Jupiter, Mercury Conjunction (1080p, 30fps)



The planets Jupiter, Venus and Mercury are close together in the evening sky this week, so every night I've been trying to capture them together on the horizon in the twilight hours before they set. The first night the clouds were too thick. The second night I was shooting sunset in high winds at Mono Lake with the Sierra Nevada as a high western horizon, so I caught a few pictures of the planets, but they set too quickly to capture a time-lapse video. The third night was just right, relatively clear to the west, I was in a high shooting position with an apparent horizon lower than my position (less than 0 degrees elevation), and fortunately that was Sunday May 16, the night when they'd be closest together, forming a tight triangle.

There was still wind to deal with so I changed position a few times to minimize it. I could only use one camera because I had loaned my daughter one of my quick release plates the day before and it was still on her camera back home. There wasn't a lot of light and I was shooting with a 2X teleconverter on my 70-200mm lens at close to 310mm, so my aperture was limited to f/8, forcing me to bump up the ISO to minimize shutter speed in that wind. Fortunately I worked out all the trade-offs in time to capture about four hundred frames, enough to create this time-lapse video. 


Here's how my four days of effort to capture this event turned out:

Meteor and Milky Way over the Sierra Nevada

A single image from a several hour, 438 frame timelapse I'm working on, taken while backpacking last Summer.

Flickr isn't accepting the HD video files I've been trying to upload this week. Vimeo.com only lets me upload one high definition file per week (I don't have a revenue stream for video to justify upgrading to unlimited), so I'm not sure when I'll a high resolution copy available. In the meantime however, you can see Vimeo's severely downgraded preview:

If this embedded player doesn't seem to play it well, try viewing it directly over on Vimeo: http://vimeo.com/18260497. For low resolution previews that Vimeo downconverts from HD, I don't recommend full screen viewing.

It looks a lot better on my laptop of course, where it actually runs slower and you can see more details such as the meteor, a satellite, and so on, so I may slow down the frame rate on the next version of this that I create.

In Search of Cathedral Peak Reflections

I started the day up near Saddlebag Lake to shoot a sunrise timelapse sequence on a nearby ridge. Then I hiked in to explore the lakes up by the old mining camp of Bennettville, hiking out in time to move to Tuolumne Meadows for a Cathedral Lakes sunset hike.

I arrived at Cathedral Lakes early enough to scout out both lakes. I arrived at Lower Cathedral Lake to find a enthusiastic welcoming committee of ravenous, probably disease-ridden, blood-sucking bugs. The few surviving human visitors to this lake were beating a hasty +retreat, doing what will be forever etched in my mind as the "Cathedral Lake dance," an awkward combination of jogging, arm-waving, stream-hopping and loud expletives.


Spotting a reflection of Cathedral Peak accompanied by an unreal, seemingly metallic cobalt rending of sky blue in the inky tea-colored waters of a nearby stagnant pool, I decided to make some use of the rock-like camera gear which for the past 3.5 miles had only served as ballast in my daypack. Aware of the risk of picking up some rare and exotic plague from the parasites spawned in this pool of decaying primordial goo, I blithely pulled out a small vial of insect repellent to keep the little pests at bay. The repellent was 100% DEET, which I knew was roughly 3.4 times stronger than the maximum effective concentration of 29% as determined by Consumer Reports. It's not possible to repel mosquitos any better than 100%, and I might grow new organs and evolve into some awkward new life form from excessive toxic chemical exposure, but perhaps I could keep the little buggers 3.4 times farther away and reduce my odds of becoming a curiousity at the Centers for Disease Control.

The chemical haze only served to confuse the little creatures, which continued to bump into my arms and legs, sing in my ears, dicover patches of unprotected flesh around my eyes, and (the last straw) congregate on my camera and in front of the lens.

I made quick work of the mosquito pond, checked the map for a possible direct route to the upper lake, and struck out to find a game trail that would lead me over the polished granite cliffs between me and my next destination.

I arrived at the upper lake to find mosquitos slightly lower in numbers, but no less annoying, so I kept moving farther up the westward granite slope to get farther and farther from their home. Eventually I ended up on a large and more or less flat rock way up the slope, killing time before sunset by killing mosquitos, and counting the ones resting on my camera and tripod (up to 12).

The wind picked up however, so I had to move down to the lake to increase my odds of finding some calm water to get the reflection that I had gone up there for. Fortunately the wind calmed down for a few minutes right when I needed it to, so I was able to catch a few good shots before making the long, dark hike back out to the trailhead at Tuolumne Meadows.


Second Try at Minaret Lake

After getting shut out on my attempt to make a visit to this lake realtively easy from the adjacent canyon, I returned a few days later to make the long, hot 7.5 mile hike up from the bottom, via Devil's Postpile National Monument. This time I camped in the monument ot be able to drive my own vehicle in, which greatly simplified logistics (and enabled me to use a bear box to safely store food away form my vehicle, an option which was lacking on the prior week's trip when the ranger station advised me to park at Mammoth Mountian and take the shuttle in).

It would be a 15 mile round trip, so I budgeted two nights in case I might want a layover day to go explore nearby lakes.


In the end however I decided that I wanted to make sure tha I got to Yosemite and Cathedral Lakes more, so I hiked back out the daya after arriving, and headed back to the Tioga Pass/Saddlebag Lake area to catch sunrise and get ina hike to the old mining camp of Bennettville before making the Cathedral Lake hike in time for sunset.

Quick Overnight to Twenty Lakes Basin

The subtraction of Minaret Lake from my John Muir Wilderness trip left me with an extra day on my hands. On the exit day from Devil's Postpile National Monument I headed up to Rock Creek to catch Little Lakes Valley at dawn while the peaks had snow on them, then I headed up to Saddlebag Lake at 10,000 feet to catch the boat taxi down the lake to the Twenty Lakes Basin. The mosquitos were thick and aggressive, as was becoming a theme for the season. I had just enough time to catch a couple of Brook Trout or dinner, make camp, and prepare for an early sunrise (sleep).



By dawn I made my way up to Conness Lakes, and I worked my way to one of the upper lakes to catch one with snow and ice still on it. Descend, break camp, hike out, catch the boat taxi, and off to the next location!

The Trail Succumbs to Snow

Descending from Garnet lake to Shadow Lake, the mosquitos were becoming more numerous and persistent, so it was a fast trip. Taking a right turn up the canyon, I completed the roughly 5 mile trip to Ediza Lake. There was no access to the northside of the lake and there still quite a bit of snow on the north-facing and east-facing slopes, so campsites were difficult to come by. The wind was strong, but the mosquitos were stronger. I had a brief moment of relative calm winds and water to catch some reflected light on the far shore, then I retreated to the safety of the tent to prepare for dawn, which fortunately arrived calm and clear. It wasn't cold enough for the snow to re-freeze solid, and I hadn't carried crampons or gaitors on this trip, so I decided not to traverse the snow and pass up past Iceberg Lake, and to put off a visit to Minaret Lake.


Gem on the John Muir Trail

Next on the itinerary was Garnet Lake. Following the John Muir Trail from Thousand Island Lake to Garnet Lake was an easy two miles and change, so I had time to shoot a few pictures at Ruby Lake along the way, and to catch some Brook Trout for dinner once I arrived. Fortuantely a guide-led tour of hikers arrived to help finish dinner so I could run off to catch sunset.


It wasn't clear whether or not sunset color would punch through the clouds, but in the nick of time the sun came through and the skies really lit up. I had a few short minutes to run around and see how many compositions I could capture. There were far more than I could do justice to, but I knew that I was bound to have a couple of keepers.

I returned to camp to enjoy some nice "blue hour" light, with a faint echo of sunset light from the distant horizon still painting the bottoms of the clouds.

For sunrise I moved further west along the northern shore of the lake, enjoying the changing light on Banner Peak and on the lake's islands.

Starting Backpacking Season with a Bang


First Morning Dawn, originally uploaded by Jeff Sullivan.

I was determined this Summer to do a fair amount of backpacking to reach some of the most scenic portions of the High Sierra. Although trail accessibility was delayed somewhat by a healthy Winter, I was determined to get up to a few lakes before the snow on the surrounding peaks was entirely gone. For the first trip I decided to do a loop out of Devil's Postpile National Monument starting on July 10, from Agnew Meadows to Thousand Island Lake, Garnet Lake, Ediza Lake, and possibly cross-country over to Minaret Lake. Much of the trip would be in the vicinity of 10,000 feet in elevation, so I built an extra acclimation day into the schedule.

I could only get a wilderness permit to enter on the Pacific Crest Trail, so I'd start off with an eight mile day rising a couple of thousand feet. That portion of the trial was exposed, hot, my packing wasn't as Spartan as it should have been, and I was carrying five days of food, so it was a long haul. Obtaining the wilderness permit, taking the requirted bus shuttle into the park, and the hike itself led me to arrive jsut before the sun went down. There was wind on the lake, so I'd have to wait until morning for the best conditions and light. Fortunately the dawn conditions didn't disappoint, with the snow-clad Banner Peak reflecting in the still waters of the lake, an angular cloud providing additional light-catching capability and interest.



During the day I navigated cross-country up to a nearby ridge to catch a view over Sullivan Lake and down to the June Lakes Loop. I ruturned in time to catch alpenglow in the sky over a small iceberg.









Fortunately the skies that night were clear and no moon was visible, so the starts were incredible: bright and endless in number. The lake was calm, so the Milky Way reflected clearly in its waters. With a start like this, I couldn't wait to see what the next days would bring!

Aggressive Black Bears in the Sierra Nevada

Mama Bear #31 Mama Bear #31, originally uploaded by Jeff Sullivan.

Typically black bears in California's Sierra Nevada are considered relatively harmless. Yosemite National park for years encouraged campers to chase them out of their campsites, as if they were large, furry stray dogs. The legality of bear hunting in adjacent national forests encouraged bears to teach each generation of cubs to be wary of humans.

The death of a bear by stoning at the hands of a boy scout troop in recent years encouraged Yosemite to retract their policy of having campers aggressively defend their campsites from bears. Expanding designation of wilderness areas has further decreased human aggression towards bears, resulting in the doubling of bear populations since the 1980s, and greater competition for food. A greater number of much bolder bears pursuing a limited food supply has resulted in an absurd numbers of vehicle and home break-ins by bears every year.

The management practices in Yosemite National Park alone have resulted in roughly 1000 vehicle break-ins by bears per year there since the late 1990s. Yosemite management focuses on the positive and notes that bear incidents are down, but as you check into campgrounds in Yosemite Valley you can still see that season's scorecard, with the numbers passing the 600 and 700 mark every Fall. Yosemite officials blame visitors, urging them to remove food from their vehicles, but even after decades of having this problem Yosemite has failed to place an adequate number of metal "bear boxes", and they've even where a few have been provided such as Curry Village, management has failed to adequately distribute them around the parking lots to encourage and facilitate their use, revealing the problem as being as much due to egregious mismanagement as anything else.

There have also been a number of attacks on humans by bears, including one last week in a campground in El Dorado County. The count was approximately a doxen from 1980-2003, but there were only 3 in the 10 years from 1983-1993, seven from 1993-1996, and with attacks in 2007, 2008 , 2009 and 2010, the rate remains troubling. Bear attacks also occur in other states such as New Mexico and Colorado, and the Sierra Club is now recommending that everyone who enters bear country carry pepper spray designed for the long distance shots needed to repel bears. Bear spray has been proven to be more effectve than guns. Protect yourself.

Smoky Owens Valley Morning

This morning started with smoke from a forest management fire the night before having settled with the coldest air down towards Crowley Lake, so I decided to stay a little higher at first so I could shoot towards the Sierra Nevada without much optical interference. I visited an area of nice cracked mud patterns.


Next I visited a pond where I could find a nice reflection shooting towards the Sierra Nevada as they caught the rising sun.

I was fortunate to also find a pair of American Avocets performing a courtship dance.
Once the sun was up I moved over to a large pond where, wind conditions permitting, I might zoom in on a reflection featuring the backlit smoke against a minimalist horizon.


Next I moved to a very small vernal pool that I had shot at a year earlier under more cloudy conditions, but this time the shot would ahve a totally differnt feel, as I'd catch the snowy Sierra contrasted against a blue sky.

Fall Colors in the Eastern Sierra

I arrived at North Lake October 1, only to discover that I missed the peak color by a day or two due to a wind storm that blew off the best red to yellow colors on the far hillside. The color present a few days ago seems to have partially blown off the trees, partially turned towards brown, but there were still some green leaves, leaving the possibility of more color in a few days.

You can find decent color in patches if you look hard enough, but the best color might not be until more of the green starts to change at lower elevations, perhaps late next week?

By the time I returned here Sunday morning, there was about 2-3" of snow by the lake. The same thing happened last year, a dusting of snow around the end of September, early October. It was a little heavier this time, and there were prints from a dozen horses and mules as the packer started in around dawn to rescue their customers from the likely 4-6" of snow higher up. There were about 6-8 snow-covered cars in the parking lot by the pack station, people off in the backcountry, most likely experiencing heavier snow. I'd like to see their pictures!

Perseid Meteor Shower III HD Video

This is my third and longest timelapse sequence yet from the Perseid Meteor Shower in August. I'll try to have sequences four and five done soon.

Make sure you have the HD display switched on (click on the HD symbol).

One of my first videos of this event was featured on Discover Magazine's blog.

Bear in mind that this is a timelapse video, so in playback as video everything is dramatically sped up. Each frame is a 15 to 30 second shot, but the video is assembled at a relatively slow frame rate of only 12 shots per second, so in video formats that play at 24 to 30 frames per second, the meteors show up for roughly two frames. In other words, each second of video displays ten to twenty minutes of shooting time. Apparently our eyes and minds are quick enough for us to perceive the meteors with some persistence even though they show up for only 1/12th of a second.

Anything that travels across the screen or survives in the video for more than a brief flash is a jet or satellite (and you can't see many of the meteors in most online copies of the video, unless you follow the links to Flickr and enable the highest HD playback available there). I'll try to find video hosting sites that enable blogging of copies that offer higher resolution playback, preferably full 1920 x 1080 HD. I'll also try to find some nice background music avalable under the Creative Commons CC-BY license (which does not seem to be a trivial search).

Meanwhile, if you'd like to explore timelapse photography yourself, download the free VirtualDub software which can convert a sequence of JPEG files into video, and check out the forum on Timescapes.org for discussions on techniques. You'll need a tripod of course, and your sequence of still images will turn out best if you use a remote switch that has an intervalometer (timer) function.

Perseid Meteors Near Tioga Pass: HD Video Timelapse II

To avoid smoke from forest fires in California I traveled to this location at an elevation of 10,000 feet near Tioga Pass in the Sierra Nevada.

To increase the visibility of the meteors, click through to the video's Flickr page and make sure you have the HD display switched on (click on the HD symbol). Then look near the center of the right half of the video to see the most meteors.

This sequence was assembled from 517 21 megapixel photos. The rescaling down to 1280 x 720 for uploading to Flickr helps eliminate much of the noise. The photos on this night were exposed for 10 to 20 seconds at an ISO sensitivity of 3200.

This was taken on the peak night for the meteor showers, but the moon makes all but the brightest meteors difficult to see, especially at these lower resolutions.

Breaking Sunrise Storm in the Owens Valley

The Summer "monsoon season" can be a very productive time to shoot in the Eastern Sierra, as small thunderstorms build and then break as warm, moist air crosses the mountains.

Return of the Flies

Alkali flies are hatching by the millions on Mono Lake, and they're just starting to form a thin black line around the lake with their bodies. By fall they'll be as dense as 2 or 3 feet wide, but Mark Twain mentioned that they were 6 feet wide around the lake when he visited.
