CHARACTERIZING BOULDER DEPOSITION TO ASSESS ROCK-FALL HAZARD IN UPPER PINES CAMPGROUND, YOSEMITE NATIONAL PARK, CALIFORNIA CORDES, Shaun E., STOCK, Greg M., SCHWAB, Brandon E., and BURKE, Raymond M. Humboldt State University Department of Geology 1 Harpst St, Arcata, CA

Purpose To differentiate between boulders of potential glacial and rock fall origin in order to assess geologic hazards within the Upper Pines campground (UPC) Boulder in Curry Village from 2008 rock fallBoulder in Upper Pines Campground

Hypotheses Boulders in Upper Pines Campground could have been transported by two primary processes: (1)glacial ( >15 ka – Last Glacial Maximum) (2)rock-fall (<15 ka) Field and GPS mapping XRF analysis Cosmogenic 10Be exposure ages Methods

Mapped Boulders in Upper Pines Campground Angularity Sub Rounded Sub Angular

Exposed Volume of Boulders

Glacially transported (~12 km) Cathedral Peak Granodiorite. Yosemite Valley was deglaciated ka Huber, 1987; Wieczorek and Jager, 1996; Stock and Uhrhammer, 2010

XRF analysis in order to determine source location of largest boulders: sample locations

Half Dome granodiorite (Khd) and Glacier Point granodiorite (Kgp) contact

Age of Boulders UP-Cosmo-1 10,917 +/ UP-Cosmo-2 9,607 +/- 954

UP-Cosmo-1 UP-Cosmo-2

UP-Cosmo-1 Age: 10,917 +/ XRF: falls within Gray et al. Khd data UP-Cosmo-2 Age: 9,607 +/- 954 XRF: intermediate between Khd/Kgp Contact ~460m above UPC

Half Dome granodiorite (Khd) and Glacier Point granodiorite (Kgp) contact

Provisional Conclusion Large boulders in the SW corner of the Upper Pines Campground are post-glacial and ~10 ka in age. XRF analysis suggests that UP-Cosmo-2 was near the Khd/Kgp contact ~460m above Upper Pines on Glacier Point Rock fall appears to be the more likely origin for large boulders in the SW corner of the campground.
