Mono Lake

The Mono Lake Tufa State Natural Reserve, which was established in 1982, is one of 70 parks, historic buildings and monuments that California State Park officials plan to close by the end of June 2012 due to budget restraints. The famous south shore tufa will still be accessible (as will the rest of the lake), but the visitor center and information kiosks will likely close and with them a valuable educational resource that has helped keep Mono Lake alive.

Since the early part of the 20th century, the water rights along the eastern Sierra Nevada mountains have been hotly contested with the construction of the Los Angeles aqueduct. The classic story of how Mulholland bought up the ranch lands of the Owen’s Valley to build his dream and bring water to the desert of Southern California is well-documented in the movie Chinatown, and the subsequent LA Department of Water and Power has been in court many times over the years as a result.

Mono Lake has no outlet and its proximity near the start of the LA aqueduct makes it critically dependent on the naturally flowing streams that feed into it from the nearby Sierra. It’s highly saline waters are a perfect breeding ground for brine shrimp, which in turn are the staple diet for over 2,000,000 migratory birds that visit the lake each year (including the second largest nesting population of California gulls in the US).

Fortunately we’ve had a couple of very wet winters and Mono Lake is receiving the water it needs for now. But with the growing demand of a rapidly expanding and thirsty west, its future remains uncertain.

Frozen in Time

Log sections on Blue Mesa, Petrified Forest National Park, Arizona

It’s hard to imagine that the vast desert that surrounds you as you whisk along Interstate 40 in Arizona was once a primordial swamp. During the Late Triassic period, about 225 million years ago, this area was a lush forest that was home to many large amphibians and early dinosaurs. The colorful Chinle Formation, which gives the Painted Desert its warm hues, also contains the sediments that have preserved the fossil trees, plants and animals of this ancient time.

At the center of this lunar landscape lies Petrified Forest National Park, which was set aside in 1962 to preserve the unique remains of this otherworldly place. In addition to its colorful badlands and fossil remains, the park also contains more than 600 archaeological sites, including petroglyphs and pit houses from some of its earliest pueblo inhabitants.

Devil’s Postpile

Cliff and columnar basalt, Devil’s Postpile National Monument, California

This small national monument near Mammoth Lakes in the eastern Sierra Nevada is celebrating its centennial this week. It was spared a watery burial one hundred years ago today when congress saved it from a proposed dam on July 6, 1911.

Its unusual basalt columns are the by-product of an ancient lava lake, which rapidly formed and then cooled leaving behind the perfectly shaped hexagonal pillars that make up the cliff. The constant force of winter freeze and thaw is slowly eroding the formation, and the symmetrical blocks that look as though they were snapped together are littered at its base like a child’s building blocks.

The road to the monument, which is closed in winter but easily accessible the rest of the year, is just past the Mammoth Mountain ski area and is also the jumping off point for the popular Minarets and Ansel Adams Wilderness.
