Insights Into Rhyolite Magma Dome Systems Based on Mineral and Whole Rock Compositions at the Mono Craters, Eastern California
ABSTRACT INSIGHTS INTO RHYOLITE MAGMA DOME SYSTEMS BASED ON MINERAL AND WHOLE ROCK COMPOSITIONS AT THE MONO CRATERS, EASTERN CALIFORNIA The Mono Craters magmatic system, found in a transtensional tectonic setting, consists of small magmatic bodies, dikes, and sills. New sampling of the Mono Craters reveals a wider range of magmatic compositions and a more complex storage and delivery system than heretofore recognized. Space compositional patterns, as well as crystallization temperatures and pressures taken from olivine-, feldspar-, orthopyroxene-, and clinopyroxene-liquid equilibria, are used to create a new model for the Mono Craters magmatic system. Felsic magmas erupted throughout the entire Mono Craters chain, whereas intermediate batches only erupted at Domes 10-12 and 14. Mafic magmas are spatially restricted, having erupted only at Domes 10, 12 and 14. Data from the new whole rock analyses illustrates a linear trend. Fractional crystallization does not replicate this trend but rather the linear trend indicates magma mixing. This study also analyzes samples from the Mono Lake Islands and the June Lake Basalts and compares them to the Mono Craters. Although the Mono Lake Islands fall into the intermediate to felsic group, they contain distinctly higher Al2O3 and Na2O at a given SiO2. Therefore, this study concludes that the Mono Craters represent a distinct magmatic system not directly related to the magmatic activity that created the Mono Lake Islands.

Backpack Trip Because It Involves Coordinating with More Agencies and Resources (Camping, Ferry, Island Transportation)
Backpack Catalina Distance: About 7 miles Trailhead: Avalon Permit Limit: unlimited Difficulty: Easy (rated 2) Features: Backpacking on Catalina Island is a classic Scout adventure. It requires a lot more planning than your typical Sierra backpack trip because it involves coordinating with more agencies and resources (camping, ferry, island transportation). Still, a great beginner trip can be planned, along with pleasant day hikes or beach time, and Avalon is a fun town for apres-hike souvenirs and dinner. FYI: The new Trans-Catalina Trail that runs the length of the island is really steep and rugged, so keep that in mind if you plan to utilize that trail. Additionally: Fuel can’t be transported on the ferry. Reserve your camp stoves and propane fuel from the Catalina Island Company. The ranger will deliver stoves, fuel, firewood and any other gear you need (and they provide) right to your campsite. Good Beginning Itinerary: Catalina Express ferry service Dana Point to Avalon; Airport Shuttle to B. J. TH Backpack 1.5 m to Black Jack Campground Day hike the Trans Catalina Trail; another night at Black Jack Backpack to Little Harbor via the Cottonwood Trail (5+ miles) or the TCT (7+ miles) Safari Bus to Avalon. Ferry from Avalon to Dana Point; drive home Important Phone Numbers Catalina Island Medical Center Hospital: 310-510-0700 100 Falls Canyon Road in Avalon In an emergency: Sheriff 310-510-0174 911 - call may go to Catalina Island or L.A.; indicate you’re on Catalina Island; GPS coordinates will be recorded Cell phone service @ Blackjack is great; okay at Little Harbor, but excellent from surrounding ridges Resources: Catalina Island Camping: 310-510-8368, M - F, 8 a.m. -

Potter General Technical Report PSW-GTR-169 Publisher: Pacific Southwest Research Station Albany, California Forest Service Mailing address: U.S. Department of Agriculture PO Box 245, Berkeley CA 94701-0245 Abstract (510) 559-6300 Potter, Donald A. 1998. Forested communities of the upper montane in the central and southern http://www.psw.fs.fed.us Sierra Nevada. Gen. Tech. Rep. PSW-GTR-169. Albany, CA: Pacific Southwest Research Station, Forest Service, U.S. Department of Agriculture; 319 p. September 1998 Upper montane forests in the central and southern Sierra Nevada of California were classified into 26 plant associations by using information collected from 0.1-acre circular plots. Within this region, the forested environment including the physiographic setting, geology, soils, and vegetation is described in detail. A simulation model is presented for this portion of the Sierra Nevada that refines discussions of climate, and disturbance regimes are described to illustrate the interaction between these features of the environment and vegetation in the study area. In the classification, plant associations are differentiated by floristic composition, environmental setting, and measurements of productivity. Differences in elevation, aspect, topographic setting, and soil properties generally distinguish each plant association described. A detailed description is presented for each plant association, including a discussion of the distribution, environment, vegetation, soils, productivity, coarse woody debris, range, wildlife, and management recommendations. A complete species list and tables for cross referencing specific characteristics of each association are provided. -

Geologic Field-Trip Guide to Long Valley Caldera, California
Geologic Field-Trip Guide to Long Valley Caldera, California Scientific Investigations Report 2017–5022–L U.S. Department of the Interior U.S. Geological Survey COVER View southwestward across Long Valley Caldera and Sierra Nevada. Caldera depression, as wide as 30 km, formed during eruption of Bishop Tuff at 767 ka. Sierra consists of Mesozoic plutonic rocks, Mesozoic metavol- canic rocks, and Paleozoic marine metasedimentary strata. Patchy white exposures in caldera are lacustrine siltstones of middle Pleistocene age that are the top of a 700-m-thick accumulation of intracaldera lake sedi- ment. Sedimentation in the deep closed depression took 600,000 years to raise lake level to its threshold for overflow around 150 ka. Outlet arm of Lake Crowley reservoir leads into Owens River Gorge, which extends 30 km southeast across a welded Bishop Tuff outflow sheet. Overflow and draining of the caldera lake reincised a 200-m-deep precaldera gorge (in Mesozoic granodiorite) that had been diverted by 3.3-Ma basalt and later blanketed by the Bishop Tuff. Round Valley Fault is 2-km-high east-facing scarp at left. At lower center of image, precaldera Glass Mountain rhyolite edifice was truncated by caldera collapse and draped by complexly incised apron of Bishop Tuff. Photo is a NaturalVue satellite image mosaic, which has been extracted from a global dataset of natural-color Landsat-7 multispectral images compiled by MDA Information Systems, Inc.
