Quick report
Sled/ski of Mt. Marston.
- We found a modest amount of windloading at the ridgetops, and crossloading on SE slopes.
- It seemed like the winds must have stopped before the overnight snow as there was 4-5 inches of new on all aspects and all elevations above 5500'.
- The warm up from sunday produced a MF crust on any slope that was able to see the sun. Shaded aspects were saved and didn't have the crust.
- We did not see any eveidence of natural avalanches from the weekend.
- Our pit on a NE aspect still showed reactivity in a PST. The weak layer we tested was the Mid Jan crust that was down 70 cm. It was easily defined as a thin ice layer with large (2-3mm) facets below it.
- Overall I don't think it got as cooked by the sun over the weekend as Peters Ridge in the Swan Range had.

Snowpack
- SE pit at 6900' had ECTX with the new 3/12 crust down 5 inches.
- NE pit at 7300' had ECTX, however, when we tested the mid Jan crust down 70 cm in a Propogation Saw Test we had unstable results (PST 20/100 END). The layer beneath the crust is 3 cm thick and composed of 2-3mm facets. It was easy to ID as the facets pretty much fell out of the pit wall.
