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.

June Lake Citizens Advisory Committee Meeting Minutes
June Lake Citizens Advisory Committee Meeting Minutes - August 5, 2014 The meeting was called to order at 7:03 pm. Committee member attendees included Ann Tozier, BZ Miller, Patti Heinrich, Jil Stark, Danny Roberts, Don Morton and Alan Sagot. Tim Alpers was also present. Minutes from the June meeting were absent, so were tabled. There was no July meeting. Public Comment: A timeshare Holder (Bettencourt??) stood up and said he was here just to see what was going on. Garret Higerd (Mono County public works) addressed the June Lake street rehab project. He said drainage is a big issue, as well as scheduling. They plan to work on one culvert this fall, with paving next construction year. They hope to be finished by the time of the June Lake Triathlon in July 2015. Jil Stark (CAC) said the Fire Safety Council meeting was this evening. They had 137 loads from the recent Chipper Weekend. Next year it will be the 3rd weekend in July (18-19th) from 10-4, to avoid the June Lake Triathlon. Julie Baldwin (fire dept) said they have a new water truck. It was outside and everyone was invited to have a look at it after the meeting. The 60th annual Fireman's BBQ is the weekend coming up. They are still looking for volunteer firemen to train. Patti Heinrich (CAC) asked for baked goods for the bake sale at the Fireman's BBQ. Agenda Items: June Lake Fuel Reduction Program update (Paul McCahon): Cal Fire mailed out a notice regarding defensible space inspections to residents. -

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.

NFWF Ranch on East Walker Now Open for Public Access
NFWF ranch on East Walker now open for public access Mason Valley News June 24, 2015 By: Keith Trout The Walker Basin Conservancy announced last week that a large portion of the Rafter 7 Ranch, which the National Fish and Wildlife Foundation purchased in early 2013 and which runs along 11 miles of the East Walker River, is now open for public access. “Visitors to that area can enjoy this well-preserved section of the East Walker River for recreational activities such as hiking, fishing and wildlife viewing,” stated a press release from the WBC of the ranch located off of the East Walker Road in far south Mason Valley. Rafter 7 Ranch, which was used for years for grazing both cattle and sheep, is privately owned by the National Fish and Wildlife Foundation and was purchased as part of the Walker River Basin Restoration Program, which is administered by NFWF and funded by Congressional appropriations. The primary purpose of the ranch acquisition is to transfer most of the Rafter 7 Ranch’s water rights instream to Walker Lake. However, according to the press release, NFWF determined the unique attributes of the property allowed for additional conservation and enjoyment of the riparian corridor and decided to work to allow public access, little of which is available along the river, as most of the river is on private land. Public access on the ranch is managed by the WBC, a nonprofit established by NFWF to manage on-the-ground operations associated with this program and provide long-term stewardship. Portions of the property will remain restricted from public access, though, as it is still an active ranch with cattle grazing and a variety of re-vegetation efforts in progress, the Walker Basin Conservancy reported. -

September 9, 2015 Dear Media Partner, Thanks for taking the time to learn about Diamond Peak Ski Resort and what makes it unique in the Lake Tahoe ski market. If you have never experienced Diamond Peak, this press kit will be a good introduction but the best way to get acquainted with this special place is to come see it for yourself! If you ski or snowboard I’d be happy to give you a full tour of the mountain this winter. Base area tours can also be arranged for those less inclined to sliding on the snow. Diamond Peak is located on the north shore of Lake Tahoe, near the Hyatt Regency Lake Tahoe, renowned restaurants, and the highest concentration of ski resorts in North America. Diamond Peak is known for amazing views, affordable prices, and a friendly atmosphere that families of all ages love. Diamond Peak skiers can take advantage of amazing deals, stretching out a ski vacation longer without breaking the bank. Enjoy incredible deals like the Flex Pass multiday ticket, $35 BYOP (Bring Your Other Pass) deal, $64 ($69 Holidays) Adult lift ticket rate, and free lift tickets for 6 and under and those over 80 years old. You’ll see from our photos that Diamond Peak has some of the most incredible views of Lake Tahoe. Views of the lake are best seen from Crystal Ridge and Snowflake Lodge, but guests can still enjoy lake views from the beginner slopes, Base Lodge deck and even the parking lot. Our HD webcam, mounted on the top of Crystal Ridge, allows you to enjoy these views and check conditions from the comfort of your screen.
