Bailey GEOLOGIC SETTING VOLCANISM Long Valley caldera and the Mono-Inyo Craters Long Valley caldera volcanic chain compose a late Tertiary to Quaternary Volcanism in the Long Valley area (Bailey and others, volcanic complex on the west edge of the Basin and 1976; Bailey, 1982b) began about 3.6 Ma with Range Province at the base of the Sierra Nevada frontal widespread eruption of trachybasaltic-trachyandesitic fault escarpment. The caldera, an east-west-elongate, lavas on a moderately well dissected upland surface oval depression 17 by 32 km, is located just northwest (Huber, 1981).Erosional remnants of these mafic lavas of the northern end of the Owens Valley rift and forms are scattered over a 4,000-km2 area extending from the a reentrant or offset in the Sierran escarpment, Adobe Hills (5-10 km notheast of the map area), commonly referred to as the "Mammoth embayment.'? around the periphery of Long Valley caldera, and The Mono-Inyo Craters volcanic chain forms a north- southwestward into the High Sierra. Although these trending zone of volcanic vents extending 45 km from lavas never formed a continuous cover over this region, the west moat of the caldera to Mono Lake. The their wide distribution suggests an extensive mantle prevolcanic basement in the area is mainly Mesozoic source for these initial mafic eruptions.

Introducing Terminal Lakes Joe Eilers and Ron Larson
Terminal Lakes Introducing Terminal Lakes Joe Eilers and Ron Larson Study Lakes akes tend to be among the more ephemeral features of the landscape Land generally are formed and disappear rapidly on a geological time frame. However, to see groups of lakes disappear within a lifetime is typically not a natural phenomenon. Here in Oregon, we’ve witnessed the desiccation of what was formerly a 16-mile-long lake in a little over a decade. Endorehic lakes, commonly referred to as terminal lakes because they lack an outlet, are among the most vulnerable of lakes to human intervention. Because terminal lakes are usually located in arid environments where water is extremely valuable, they are the first to lose among the competing forces for water. But that doesn’t have to be the case. In some respects, terminal lakes are far easier to restore than eutrophic/hypereutrophic systems. No expensive alum treatments, no dredging, no chemicals . just add water and life returns: but as those in West know, “Whiskey is for drinking; water is for fighting over.” And fight we must. In this issue of LakeLine, we describe a series of terminal lakes in the western United States starting with the least saline lake among the group, Walker Lake, and ending with Lake Winnemucca, which was desiccated in the 20th century (Figure 1). Like all lakes, each of these has a unique story to relate with different Figure 1. Terminal lakes in the western United States described in this issue. chemistry and biota. The loss of Lake Winnemucca is an informative tale, but it a wider audience and reach a solution migration when the birds replenish fat is not necessarily the inevitable outcome that ensures adequate water to save the reserves. -

2021 Falling for the Migration
Falling for the Migration: Bridgeport, Crowley, Mono American Avocets in flight, photo by Bob Steele August 20–22, 2021 ● Dave Shuford $182 per person / $167 for Mono Lake Committee members enrollment limited to 10 participants Welcome to our field seminar on the fall migration of birds in the Bridgeport Valley and the adjacent Sierra, the Mono Basin, Crowley Lake, Long Valley, and the outskirts of Mammoth Lakes. Beginners as well as experts will enjoy this introduction to the area’s birdlife found in a wide variety of habitats, from the shimmering shores of Mono Lake to lofty Sierra peaks. We will identify about 100 species by plumage and calls, and probe the secrets of their natural history. This seminar will include informal discussions on migration strategies, behavior, and ecology that complement our field observations. This seminar will involve easy hiking at elevations ranging from 6,400 to 9,600 feet above sea level. We will hike 1–2 miles a day, mostly on level terrain. The first stop Friday morning is at Bridgeport Reservoir, a mecca for migrant and late‐breeding waterbirds. For those who prefer to meet the seminar at this location (arriving Friday morning from points north), please contact Nora Livingston at [email protected] or (760) 647‐6595 to obtain directions. Dave Shuford is an expert birder, avid naturalist and teacher, and a retired professional ornithologist. Dave’s bird research in the region includes a long‐term study on the ecology of Mono Lake’s California Gull colony, an atlas of breeding birds in the Glass Mountain area, and surveys of Snowy Plovers at Mono and Owens lakes. -
Tuolumne Meadows the Beautiful Rounded Domes of Tuolumne Meadows Offer Some of the Best Moderate Granite Climbing Any- Where
TM most practical multi-pitch solution v1.0 Tuolumne Meadows The beautiful rounded domes of Tuolumne Meadows offer some of the best moderate granite climbing any- where. Located within the Yosemite National Park, Tuolumne is a good choice if you want to escape the heat and the crowds of the Yosemite Valley, and climb in a peaceful and quiet setting during the summer months. Tuolumne is simply an amazing place of solitude and beauty, where exquisite climbing opportunities await on some of the best granite in North America. The massive granite domes and other high peaksMt areOlympus situated at an altitude of 8600 feet, where the air is cool and crisp, and the skies are clear. Tuolumne is more peaceful, relaxing, and quiet than the Valley, and you’ll be happy to be climbing in a cool alpine breeze when it’s 100+ degrees everywhere else. After a long day of climb- ing on perfect glacier polished granite, go take a hike accross the meadow, hang out at the beach at Tenaya Lake, cool down in the river or enjoy a local beer and a burger at the grill. Tuolumne Meadows is simply the perfect summer climbing destination.

In his formal plan for the Insti- tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of profes- sional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other in- terested institutions and specialists throughout the world.

Do not click links or open attachments unless you recognize the sender and know the content is safe. Dear Sir or Madam, I am writing to protest the proposal to develop and expand the "Tioga Inn" site. I have been voting the Mono Basin since 1978, first as a researcher on the gull population, later to expose my family and my students to the marvellous landscape. The proposed inn development would have serious visual impacts on the lake environment, detracting from the enjoyment of the entire region. In addition. I am concerned by the effects of additional light pollution in the basin.
