The past two Wednesday’s have offered optimal conditions to collect photogrammetry data. Attached is the snow depth change map in meters from March 23rd to 30th. The six inches of recently accumulated snow from this past Sunday was heavily wind affected and formed large dense windslabs shown in blue in the depth map. These slabs vary in depth but are typically at least 3 feet thick where the map is the darkest blue.

The aim of this data is to be used as yet another tool in backcountry travelers’ decision making. Due to the difference in surface appearance between rotten frozen ice/snow and fresh windslab, problem areas can be defined easily in the field. This is the first attempt at quantifying the exact spatial extent and depth of these slabs remotely, something that would be quite difficult on the ground. I plan on incorporating a numerical model that simulates snow transport and accumulation so that given input MWOBS meteorological values, similar models can be made without the need to fly a drone.

Thank you for all who have stopped to talk when I am flying at connection cache.

Feel free to reach out to me with any further questions or comments.
