Eastern Sierra Fall Colors

California, Sierra Nevada

I recently posted some new images from a September 2009 visit to the Bishop Creek and Rock Creek watersheds, as well as a list of resources for learning more about where and when the fall colors can be expected to appear, and how to best photograph Fall Colors in the Eastern Sierra.

I’m looking forward to seeing the aspen trees (Populus tremuloides) again in the Eastern Sierra. Here are a few of my favorites, all photographed in the Bishop Creek Canyon watershed at the peak of the 2006 fall color season.

Giant Sequoia Pictures

Sierra Nevada, Trees, Yosemite

Many of my giant sequoia pictures are now on Photoshelter, which is the source of this nifty slideshow. Sequoia trees really are the most majestic of all plants. They are the largest (i.e., most massive) life forms on earth, and they are nearly the tallest (exceeded only by their cousins the coastal redwoods in the Pacific Northwest). Giant sequoia trees are one of the longest lived organisms on earth, exceeded in longevity most notably by Ancient Bristlecone pine trees (Pinus longaeva). Enjoy images of these “pillars of the sierra”.

My website also has many giant sequoia tree photos (Sequoiadendron giganteum).

Photos of Glacial Erratic Boulders

California, Sierra Nevada, Yosemite

Some years ago I posted a blog entry about photos of glacial erratic boulders on Olmsted Point in Yosemite National Park. Well, I was recently there and got a few more. Glacial erratic boulders are so named because they are erratic (i.e., differ materially from the naturally occuring stone nearby) and they were deposited by slow-moving glaciers, sometimes after having been moved a considerable distance (e.g., tens of miles) from their place of origin. The boulders are carried by the glacier and then either fall off the side of the glacier as it slowly slides along, or are simply dropped in place if a glacier melts away. Olmsted Point, high above Tenaya Canyon, is a great location for seeing glacial erratic boulders. The same glaciers that sculpted nearby granite monoliths Half Dome and Cloud’s Rest, seen in the background of one these photos, also left behind many glacial erratic boulders on the rim of Tenaya Canyon when it passed by.

Erratics are huge boulders left behind by the passing of glaciers which carved the granite surroundings into their present-day form.  When the glaciers melt, any boulders and other geologic material that it was carrying are left in place, sometimes many miles from their original location, Yosemite National Park, California
