The Yosemite Cemetery is filled with echoes of Yosemite’s past. For American Indians the origins of these echoes reach back many hundreds, perhaps thousands of years. The echoes of non-Indians go back only to the mid-nineteenth century, yet this was a time of great change in the American perspective on wild lands and scenic resources. A visit to the Yosemite Cemetery will bring you closer to many of the personages that began the development of what we now call Yosemite National Park.

August 29 marked the 142nd Anniversary of the first recorded ascent of Mount Lyell, Yosemite’s highest peak (13,114 feet). J. B. Tileston made that ascent in 1871.

I was exploring Yosemite's mountain forests at about 5,000 feet elevation recently, when I found my favorite patch of lady slipper orchids still in bloom.

I was so taken by them that I decided to study botany in college.

Dangerous snake? It sure is... if you are a lizard, nestling bird, or small mammal. If you are a human being, it is mostly harmless. The Sierra mountain kingsnake (Lampropeltis zonata multicincta), with its rings of white, orange, and black, has to be the most spectacularly colored snake in Yosemite. Some call it the coral kingsnake because of its somewhat similar appearance to the venomous coral snake. Fortunately for Yosemite visitors, the nearest wild coral snake lives in Arizona.

Every January the Merced Canyon opens the annual flower show with waterfall buttercups (Kumlienia hystriculus). These beauties live around wet areas where water continually drips or near waterfalls where they are kept fresh by spray.

What causes rockfall on calm days in summer? When it rains and rocks fall we pretty much know that running water probably triggered it. Likewise we understand that earthquakes and the freezing and thawing of ice on cliffs can also trigger rockfall. However, there are other triggers that remain a mystery. Why is it that rocks also fall on perfectly calm summer afternoons with no apparent cause?

On October 2, 2012, local naturalist Michael Ross spotted a bird he had never seen before, at least not in Yosemite. After careful observation he determined it was a gray catbird (Dumetella carolinensis).
