08-25-19 – Chimney Peak Wilderness


The Chimney Peak Wilderness is a 13,134-acre (53.15 km2) wilderness area located 20 miles (32 km) northwest of Ridgecrest, in southeastern Tulare County, California.

The 1994 California Desert Protection Act (Public Law 103-433) created the wilderness and it is managed by the Bureau of Land Management (BLM), Department of the Interior.

The Chimney Peak Wilderness is a rugged and mountainous Mojave Desert environment on the eastern side of the Southern Sierra Nevada Range. The wilderness is named for Chimney Peak, elevation 7,871 feet (2,399 m), located in the northeast corner of the wilderness.

The area has Mojave Desert plants such as Joshua tree (Yucca brevifolia) and creosote bush (Larrea tridentata) on the valley floors and alluvial fans and in the Sierra foothills. Higher Sierra elevations have single-leaf pinyon pine (Pinus monophylla).

The Pacific Crest Trail passes through the wilderness area.

A portion of the Sacatar Trail, an old wagon road into the Owens Valley once used by soldiers and cattlemen, cross the Chimney Peak Wilderness, .

Chimney Peak Backcountry Byway
The BLM began a “byway” program in 1989 which is a tour by automobile through or near scenic public lands. This program designates “backcountry byways” along secondary roads. The Chimney Peak Backcountry Byway can be accessed from State Route 178, is over 38 miles (61 km) in length and travels through Lamont Meadow, circles around Chimney Peak, and returns to Canebrake Road at Lamont Meadow.

08-18-19 – Mono-Inyo Craters


The Mono–Inyo Craters are a volcanic chain of craters, domes and lava flows in Mono County, Eastern California. The chain stretches 25 miles (40 km) from the northwest shore of Mono Lake to the south of Mammoth Mountain. The Mono Lake Volcanic Field forms the northernmost part of the chain and consists of two volcanic islands in the lake and one cinder cone volcano on its northwest shore. Most of the Mono Craters, which make up the bulk of the northern part of the Mono–Inyo chain, are phreatic (steam explosion) volcanoes that have since been either plugged or over-topped by rhyolite domes and lava flows. The Inyo Craters form much of the southern part of the chain and consist of phreatic explosion pits, and rhyolitic lava flows and domes. The southernmost part of the chain consists of fumaroles and explosion pits on Mammoth Mountain and a set of cinder cones south of the mountain; the latter are called the Red Cones.

Eruptions along the narrow fissure system under the chain began in the west moat of Long Valley Caldera 400,000 to 60,000 years ago. Mammoth Mountain was formed during this period. Multiple eruptions from 40,000 to 600 years ago created the Mono Craters and eruptions 5,000 to 500 years ago formed the Inyo Craters. Lava flows 5,000 years ago built the Red Cones, and explosion pits on Mammoth Mountain were excavated in the last 1,000 years. Uplift of Paoha Island in Mono Lake about 250 years ago is the most recent activity. These eruptions most likely originated from small magma bodies rather than from a single, large magma chamber like the one that produced the massive Long Valley Caldera eruption 760,000 years ago. During the past 3,000 years, eruptions have occurred every 250 to 700 years. In 1980, a series of earthquakes and uplift within and south of Long Valley Caldera indicated renewed activity in the area.

The region has been used by humans for centuries. Obsidian was collected by Mono Paiutes for making sharp tools and arrow points. Glassy rock continues to be removed in modern times for use as commercial scour and yard decoration. Mono Mills processed timber felled on or near the volcanoes for the nearby boomtown Bodie in the late 19th to early 20th centuries. Water diversions into the Los Angeles Aqueduct system from their natural outlets in Mono Lake started in 1941 after a water tunnel was cut under the Mono Craters. Mono Lake Volcanic Field and a large part of the Mono Craters gained some protection under Mono Basin National Forest Scenic Area in 1984. Resource use along all of the chain is managed by the United States Forest Service as part of Inyo National Forest. Various activities are possible along the chain, including hiking, bird watching, canoeing, skiing, and mountain biking.

08-17_18-19 – Mono Lake


Mono Lake is a large, shallow saline soda lake in Mono County, California, formed at least 760,000 years ago as a terminal lake in an endorheic basin. The lack of an outlet causes high levels of salts to accumulate in the lake. These salts also make the lake water alkaline.

This desert lake has an unusually productive ecosystem based on brine shrimp that thrive in its waters, and provides critical habitat for two million annual migratory birds that feed on the shrimp and alkali flies. Historically, the native Kutzadika’a people derived nutrition from the Ephydra hians pupae, which live in the shallow waters around the edge of the lake.

When the city of Los Angeles diverted water from the freshwater streams flowing into the lake, it lowered the lake level, which imperiled the migratory birds.

Mono Lake occupies part of the Mono Basin, an endorheic basin that has no outlet to the ocean. Dissolved salts in the runoff thus remain in the lake and raise the water’s pH levels and salt concentration. The tributaries of Mono Lake include Lee Vining Creek, Rush Creek and Mill Creek which flows through Lundy Canyon.

The basin was formed by geological forces over the last five million years: basin and range crustal stretching and associated volcanism and faulting at the base of the Sierra Nevada. Five million years ago, the Sierra Nevada was an eroded set of rolling hills and Mono Basin and Owens Valley did not yet exist.

From 4.5 to 2.6 million years ago, large volumes of basalt were extruded around what is now Cowtrack Mountain (east and south of Mono Basin); eventually covering 300 square miles (780 km2) and reaching a maximum thickness of 600 feet (180 m). Later volcanism in the area occurred 3.8 million to 250,000 years ago. This activity was northwest of Mono Basin and included the formation of Aurora Crater, Beauty Peak, Cedar Hill (later an island in the highest stands of Mono Lake), and Mount Hicks.

Mono Lake is believed to have formed at least 760,000 years ago, dating back to the Long Valley eruption. Sediments located below the ash layer hint that Mono Lake could be a remnant of a larger and older lake that once covered a large part of Nevada and Utah, which would put it among the oldest lakes in North America. At its height during the most recent ice age, the lake would have been about 900 feet (270 m) deep. Prominent old shore lines, called strandlines by geologists, can be seen west of the Lake.

Currently, Mono Lake is in a geologically active area at the north end of the Mono–Inyo Craters volcanic chain and is close to Long Valley Caldera. Volcanic activity continues in the Mono Lake vicinity: the most recent eruption occurred 350 years ago, resulting in the formation of Paoha Island. Panum Crater (on the south shore of the lake) is an example of a combined rhyolite dome and cinder cone.

Tufa towers
Many columns of limestone rise above the surface of Mono Lake. These limestone towers consist primarily of calcium carbonate minerals such as calcite (CaCO3). This type of limestone rock is referred to as tufa, which is a term used for limestone that forms in low to moderate temperatures.

08-17-19 – Crowley Lake


Crowley Lake is a reservoir on the upper Owens River in southern Mono County, California, in the United States. Crowley Lake is 15 miles south of Mammoth Lakes.

The lake was created in 1941 by the building of the Long Valley Dam by the Los Angeles Department of Water and Power (DWP), as storage for the Los Angeles Aqueduct and for flood control. The dam is 126 feet high and impounds 183,465 acre-feet. For more on the history of the lake, see Owens Lake.

The lake is named after Father John J. Crowley, “the desert Padre”, who was a key figure in Owens Valley history and a local hero. When it became obvious that the city of Los Angeles’s appropriation of the water supply had made agriculture impossible in the Owens Valley, many of the residents of the Valley lost all hope. Father Crowley traveled up and down the Valley, convincing many of them that it could become a tourist destination. Thus, it is fitting that while it exists to serve the Los Angeles aqueduct, Crowley Lake is also a prime destination for anglers. Father Crowley was killed in 1940 in an automobile accident.

Upon completion of the reservoir in 1941, strange columnar formations, some of which reached heights of as much as 20 feet, were spotted along the reservoir’s eastern shore. Some described them as stone cylinders connected by fortified stone arches that had been completely covered and obscured for millions of years but which had been gradually unmasked by the incessant pummeling of the lake’s powerful waves, whose constant pounding had eroded the more malleable rock at the base of the cliffs encasing these pillars. The pillars were simply regarded as oddities until 2015, when geologists realized that they were the result of frigid water from melting snow seeping down into volcanic ash (the result of a catastrophic explosion more than 700,000 years prior), creating tiny holes in the hot ash, the byproduct being boiling water and steam, which then rose up and out of these same holes. Samples of the resulting “evenly spaced convection cells similar to heat pipes” (a quote from a study at UC Berkeley) were analyzed using X-rays and electronic microscopes; and researchers found that minute crevices in these “convection pipes” were literally bonded into place by minerals that were able to resist the corrosive force of the lake’s waves. Researchers have now counted nearly 5,000 of these pillars, which appear in groups and vary widely in shape, size and color over an area of 4000 acres, with some of the columns standing as erect as towering pylons and sporting ringed apertures approximately a foot apart; others which are warped or leaning at various angles; and still others that are half-submerged and, some say, resemble the petrified remains of dinosaur vertebrae.

06-15-19 – Alabama Hills National Scenic Area



The Alabama Hills are a range of hills and rock formations near the eastern slope of the Sierra Nevada in the Owens Valley, west of Lone Pine in Inyo County, California, United States. Though geographically separate from the Sierra Nevada, they are part of the same geological formation.

The Alabama Hills are managed by the U.S. Bureau of Land Management (BLM) as the Alabama Hills Recreation Area. The area is managed as a protected habitat for public enjoyment. In March 2019, the US congress, as part of the California Deserts Wilderness Act, redesignated the area as the Alabama Hills National Scenic Area

11-04-18 – Red Rock Canyon



Red Rock Canyon State Park features scenic desert cliffs, buttes and spectacular rock formations. The park is located where the southernmost tip of the Sierra Nevada converges with the El Paso Mountains. Each tributary canyon is unique, with vivid colors. After wet winters, the park’s floral displays are notable.
