Animal Ethology Reflected in the Rock Art of Nine Mile Canyon, Utah

This study of the rock art of Nine Mile Canyon, in central eastern Utah, focuses on scenes depicting bighorn sheep and other large game animals, important resources to Great Basin Native American groups. Much of the rock art discussed is thought to have been created by members of the Fremont culture, although some was created by later Numic people. The results of this study suggest that the Nat...

Refraction tomography mapping of near‐surface dipping layers using landstreamer data at East Canyon Dam, Utah

We apply the P-wave refraction-tomography method to seismic data collected with a landstreamer. Refractiontomography inversion solutions were determined using regularization parameters that provided the most realistic near-surface solutions that best matched the dipping layer structure of nearby outcrops. A reasonably well matched solution was obtained using an unusual set of optimal regulariza...

Mars Pathfinder Near-field Rock Distribution Re-evaluation

Introduction: We have completed analysis of a new near-field rock count at the Mars Pathfinder landing site and determined that the previously published [1,2] rock count suggesting 16 % cumulative fractional area (CFA) covered by rocks is incorrect. The earlier value is not so much wrong (our new CFA is 20%), as right for the wrong reason: both the old and the new CFA’s are consistent with remo...

Crustal loading near Great Salt Lake, Utah

[1] Two sites of the BARGEN GPS network are located 30 km south of Great Salt Lake (GSL). Lake-level records since mid-1996 indicate seasonal water elevation variations of 0.3 m amplitude superimposed on a roughly ‘‘decadal’’ feature of amplitude 0.6 m. Using an elastic Green’s function and a simplified load geometry for GSL, we calculate that these variations translate into radial crustal load...
