RTK-GPS measurements on 6 rock glaciers in the La Sal and Uinta Mountains, Utah between 2021 and 2023

RTK-GPS surveying of points marked on the surfaces of 6 rock glaciers in the La Sal and Uinta Mountains, Utah

All  measurements made with a pair of Emlid Reach RS2 RTK-GPS receivers connected in FIX mode

Comparison of the x/y coordinates for points in subsequent surveys reveals planimetric motion of the rock glacier

Error on measurements in the z direction (vertical) is large enough that up/down changes in the rock glaicer surface cannot be quantified from these data alone
