At 0515, running depth was 2.0", then 2.5" at 0611 official observation time. Very difficult to obtain consistent Total SWE due to ~1" of hard, dense, clear ice under the snow.
1/29/2019 6:06 AM 0.18 5.4 0.23 9.5 1.00 Exactly 1.00" SWE of total snow depth from 9.5" core. Difficult to obtain a core with integrity, as there is a layer of fresh snow on top of a layer of very firm crusty old snow, with a 1" ice layer at the bottom. Hard to tell if the bottom layer was 100% obtained. Had to chip around the perimeter of the gauge to isolate and collect.
