Use of Radiocarbon Ages to Narrow Groundwater Recharge Estimates in the Southeastern Mojave Desert, USA
hydrology Article Use of Radiocarbon Ages to Narrow Groundwater Recharge Estimates in the Southeastern Mojave Desert, USA Adam H. Love 1,* and Andy Zdon 2 1 Roux Associates, Inc., 555 12th Street, Suite 250, Oakland, CA 95607, USA 2 Partner Engineering and Science, Inc., 1761 E. Garry Avenue, Santa Ana, CA 92705, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-415-697-6200 Received: 2 August 2018; Accepted: 10 September 2018; Published: 13 September 2018 Abstract: Estimating groundwater recharge in arid or semiarid regions can be a difficult and complex task, since it is dependent on a highly variable set of spatial and temporal hydrologic parameters and processes that are dependent on the local climate, the land surface properties, and subsurface characteristics. As a result, traditional methods for estimating the recharge can result in a wide range of derived values. This is evident in the southeastern Mojave Desert, where calculated recharge estimates by previous investigators that range over an order of magnitude (from ~2500 to ~37,000 acre feet per year) are reported. To narrow down this large span of recharge estimates to narrower and more plausible values, this study evaluates the previous recharge estimates in this region, to examine the sources of variability in the reported results and to constrain the recharge estimates based on the hydrologic conditions and the radiocarbon age-dating of spring flows—even without knowledge of the precise subsurface hydrology. The groundwater age and perennial flow characteristics of springs in this study could not be derived from waters sourced solely from local recharge. -

Mojave National Preserve California
A fact sheet from 2017 Dougall Photography/iStockphoto Mojave’s $131.8 million maintenance backlog includes repairs to historic buildings such as the Kelso Depot. Shane McMurphy/iStockphoto Mojave National Preserve California Overview Two hours from the hustle and bustle of Las Vegas and 100 miles from the nearest lodging lies California’s Mojave National Preserve. The Las Vegas Review-Journal dubbed this vast desert in San Bernardino County the “perfect escape for those seeking serenity.” The preserve spans 1.6 million acres, making it the third-largest National Park Service (NPS) unit in the contiguous United States. Mojave is ecologically and geologically diverse, with towering sand dunes, dun-colored mesas, and volcanic formations providing habitat for its abundant plants and wildlife. In addition to the densest forest of Joshua trees in the world, visitors can see bighorn sheep, bobcats, golden eagles, and breathtaking displays of seasonal wildflowers. The preserve also has a rich cultural heritage. Lands first inhabited by the Chemehuevi and Mojave tribes attracted gold miners in the late 19th century and were later crossed by several railroad lines. Visitors can learn more about this history through exhibits at the visitor center and by exploring archaeological sites, abandoned mines, and preserved homesteads and other buildings. The ghost town of Kelso, which once served as a Union Pacific Railroad depot and mining outpost, is one of the park’s most popular destinations. Unfortunately, Mojave faces over $131 million in deferred maintenance. Maintenance challenges Nearly all of Mojave’s needed repairs are for its road network. Severe deterioration of some sections of pavement has prompted the NPS to warn visitors of dangerous potholes. -
Proceedings of the Indiana Academy of Science
Sand Ernest Rice Smith, DePauw University In retracing some of the "footprints in the sands of time," my mind goes back to a conversation some two years ago with my aunt, then eighty-four years young. She referred to "maple sand," a common "pest" to the maple-syrup makers in Vermont. The implication was that this "sand" had come up as sand from the soil through the circulatory system of the maple tree and then settled out in the boiling down of the sap. The resulting argument, as in so many cases, was based merely on lack of definition of terms. There is such a thing as maple sand, but it has not come up as sand from the soil. It's a fine, white, crystalline, rather impure calcium malate which, because of its relative insolubility (as compared with sugar) precipitates before the sugar in the syrup and sugar making. The solubility of calcium malate at 0°C. is 0.812 gm. per 100 cc. of water as compared with a solubility of sucrose, under the same conditions, of 179 gms. This relative difficulty of solution of the calcium malate as compared with sugar will explain the feeling of the maple-sugar maker that it is as insoluble as sand and the resultant naming of the material, "sand." Examination of two specimens of maple sand indicates a material much finer than what is usually called sand. 1 Table I.

Lanfair Valley Groundwater Basin Bulletin 118
Hydrologic Region Colorado River California’s Groundwater Lanfair Valley Groundwater Basin Bulletin 118 Lanfair Valley Groundwater Basin • Groundwater Basin Number: 7-1 • County: San Bernardino • Surface Area: 157,000 acres (245 square miles) Basin Boundaries and Hydrology This basin underlies Lanfair Valley in eastern San Bernardino County. The valley slopes southeasterly with valley floor elevations ranging from 3,500 to 5,000 feet above sea level. The basin is bounded by impermeable rocks of the New York and Castle Mountains on the north, of the Piute Range on the east, of the Hackberry Mountain on the south, and of the Providence Mountains and Mid Hills on the west. Caruthers Creek flows intermittently southeastward during periods of heavy precipitation. Piute Spring discharges groundwater from Lanfair Valley to an adjacent valley and other smaller springs are found throughout the valley. Average annual precipitation ranges from 7 to 10 inches. Hydrogeologic Description Water Bearing Formations The primary water-bearing formations are Quaternary and Tertiary age unconsolidated deposits that include highly indurated sand, silt, clay and gravel. The maximum thickness of these deposits is not known; however, a boring log indicates a thickness of at least 550 feet locally. Wells in these deposits yield about 3 to 70 gpm (Friewald 1984). Restrictive Structures The Cedar Canyon fault crosses the northwest portion of the basin; however, it is unknown whether or not this fault is a barrier to groundwater. Recharge Areas The principal sources of recharge are likely percolation of runoff from surrounding mountains, percolation of precipitation to the valley floor, and subsurface inflow from adjacent basins. -

Mojave National Preserve Management Plan for Developed
Mojave National Preserve—Management Plan for Developed Water Resources CHAPTER 3: AFFECTED ENVIRONMENT Introduction This chapter describes the unique factors that influence water resource management in the Preserve and the resources that could be affected by the implementation of any of the alternatives described in Chapter 2: Alternatives. The resource descriptions provided in this chapter serve as a baseline to compare the potential effects of the management actions proposed in the alternatives. The following resource topics are described in this chapter: • Environmental Setting • Cultural Resources • Water Resources • Wilderness Character • Wildlife Environmental setting and water resources are important for context and are foundational for water resource management, but are not resources that are analyzed for effects. Resource issues that were considered and dismissed from further analysis are listed in Chapter 1: Purpose of and Need for Action and are not discussed further in this EA. A description of the effects of the proposed alternatives on wildlife, cultural resources, and wilderness character is presented in Chapter 4: Environmental Consequences. Environmental Setting The Preserve includes an ecologically diverse yet fragile desert ecosystem consisting of vegetative attributes that are unique to the Mojave Desert, as well as components of the Great Basin and Sonoran Deserts. Topography The topography of the Preserve is characteristic of the mountain and basin physiographic pattern, with tall mountain ranges separated by corresponding valleys filled with alluvial sediments. Primary mountain ranges in the Preserve, from west to east, include the Granite, Kelso, Providence, Clark, New York, and Piute Mountains. Major alluvial valleys include Soda Lake (dry lake bed), Shadow Valley, Ivanpah Valley, Lanfair Valley, and Fenner Valley.
