Where these numbers come from Depth, new snow and snow water equivalent are read from the Lone Mountain NRCS station at 8,820 ft, synced every six hours and run through range and spike checks. A station sits at one elevation, so it can disagree with the resort’s own upper-mountain report. How PeakCam reads the sensors .
