Skip to main content. Valley-fill deposits, exposed by Twentieth-Century dissection of a number of meadows on the west slope of the southern Sierra Nevada, contain a stratigraphic record strongly affected by secular variations in watershed hydrology during the Holocence. Meadows are situated in low gradient reaches, adequately supported by seepage water, where fine textured materials accumulate under present hydrologic conditions. Meadows do not necessarily owe their origin to glacial modification of drainage. Many meadows have formed in both glaciated and unglaciated valleys by a water table rise in valley-fill deposits. Ground water in any meadow drainage basin is annually recharged by snowmelt. Significant evapotranspiration by meadow plants causes diurnal fluctuations of growing-season water tables on the order of 0. Growing-season water-table depths are characteristically different for the two major plant communities, being usually shallower that 2 feet for meadows, and deeper than 4 ft for conifer forests. This relationship and a ground-water model are used to interpret paleohydrologic variations recorded in valley-fill stratigraphy. Stratigraphy, radiocarbon dating, and tephrachronology indicate the following sequence in upper tributary valleys of the montane belt.

The Sierra Nevada is the highest mountain chain in the Iberian Peninsula with higher elevations found only in the Alps. Declaration Date : Surface Area: , The steep mountain slopes area reflection of its past, modelled by glacial erosion. The dominating climate is continental Mediterranean, althoughit has strong variations in mean annual rainfall, ranging with altitude between and 1, mm. The vegetation includes vast stretches of grasslands and highmountain scrubland, Pine, Juniper and deciduous and sclerophyllus forests.
But what confers an extraordinary value on the Sierra Nevada, in addition to its grandiosel andscapes, are the numerous unique and endemic species of flora found here, with over 1, different species recorded, 64 of which are endemic.

The Mimosa House in Rancho Cordova has you covered with delicious food, a fun atmosphere, and—of course—plenty of bubbles to toast the day ahead. After breakfast, take your date to literal new heights with a hot-air balloon ride. Sky Drifters in nearby Rancho Murieta offers the unforgettable experience of floating through the skies with a licensed pilot over the gorgeous Sierra Nevada foothills. Group flights give a lively vibe, or you can opt for a private flight for just the two of you and the pilot, of course.
After your flight, continue with the up-in-the-clouds theme at Sky Sushi. This hip sushi bar is one of the top-rated restaurants in Rancho Cordova, providing an intimate, romantic vibe and delicious sashimi, specialty rolls, and creative seafood dishes. Culturally-minded types are sure to be impressed when you take them to the Root of Happiness Kava Bar.

After being closed for more than two months due to the coronavirus pandemic, Yosemite National Park will reopen at 7 a. We are very glad to be able to provide that to as many people as we can safely. Reservations for day-use passes in June and July can be made at www. Up to 1, vehicle passes will be issued each day for day use, and another 1, vehicles are expected for people with overnight reservations for hotels and camping in the park.
Visitors who arrive at the park with proof of overnight reservations or day use reservations — preferably a printed out email confirming a hotel, campground or day use reservation — will be let in.

The location is not the only thing that makes Sierra Nevada different. The Granada resort, apart from having a total of skiable kilometres and ski slopes (
Mark your calendars! The source and transport of mercury in Sierra Nevada watersheds, from hydraulic mine sites to foothill reservoirs and beyond, has detrimental implications for ecosystem resiliency and community health. The first day of the conference will feature technical presentations that encourage robust discussion of each specific strategic target.
The second day will include a tour designed to provide participants with a tangible, on-the-ground opportunity to discuss mercury abatement. Reclaiming the Sierra builds on over a decade of research to understand the legacy of historic mining and to catalyze action for headwater management that reduces impacts from mine-scarred lands while promoting the resiliency of natural and human resources from the Sierra to the sea.
This has been distilled into a specific and detailed strategy document that outlines actions and projects to reduce mercury discharge. The strategy is supported by a wide range of conservation, government, and academic organizations. The Sierra Fund’s mission is to restore ecosystem and community resiliency in the Sierra Nevada region. Menu Skip to content.

Scientists from the University of Granada, the IGME, and the Universities of Cologne and Lisbon have demonstrated that the careo irrigation channels of Sierra Nevada constitute the oldest underground aquifer recharge system on the continent. A multidisciplinary group of scientists from the Geological and Mining Institute of Spain IGME and the Universities of Granada, Cologne, and Lisbon has demonstrated that the traditional careo underground aquifer recharge system used in Sierra Nevada is the oldest in Europe.
This finding is the outcome of various research techniques conducted by experts from different fields including archaeology, sedimentology, geophysics, and hydrogeology. For centuries, this practice of recharging mountain aquifers has been conducted in several regions of our planet, although the most-documented cases are found in the high-Andean regions of Peru and Ecuador. In Sierra Nevada, water is sown and harvested by means of the so-called acequias irrigation channels de careo. These acequias , dug out of the ground, are used by mountain stock farmers and acequieros the individuals with expert skills in water catchment and allocation to channel the meltwater so that it seeps down through the high part of the valleys.
Once the water has percolated through the subsoil, it trickles down the mountain slopes to, eventually, feed the rivers and springs. This increases their flow during the dry season, when it is most needed. The archaeological and historical research conducted on this project has shown that there were acequias de careo operating in Sierra Nevada as early as the 11th Century. However, the innovative dating techniques used in the study went a stage further, calculating how long the grains of quartz sediment that were dragged here by the early acequias have remained buried.
These calculations show that the practices of sowing and harvesting water on Sierra Nevada date back about 1, years. That means this system was first implemented during the transition period between the end of the Visigoth period and the beginning of the period associated with al-Andalus.

In , the Southern Nevada Water Authority SNWA began buying water rights in rural Nevada and developing a plan to export the groundwater via a mile-long pipeline across public land for domestic and industrial use in the Las Vegas metropolitan area. Fighting over the pipeline has spanned generations of stakeholders and brought together a rare coalition of rural and urban Nevadans in a common cause.
Opponents of the project argued that drawing down groundwater below recharge levels in several rural valleys came with unacceptable environmental, ecological, cultural and economic impacts. A coalition of grass-roots organizations stopped the plan over decades of battles in the Nevada State Legislature, in courts, and in the Nevada Division of Water Resources.
