We spent a nice morning riding the new, light powder in the northern Bear River Range. We found great powder and improved coverage. The snow was light and rode fast. We didn't see any evidence of recent avalanches but the visibility was not great, with only a few glimpses with good lighting. We did experience a couple of heart-stopping whumps today, but luckily we were in very low-angled areas that couldn't slide. We dug a pit on a northeast slope at about 8100 feet in elevation. There was approximately 52 inches of total snow on the ground in this location and the slope angle was 23 degrees. We immediately noticed many obvious layers throughout the snowpack when we dug our pit. We conducted 2 compression tests and had failures on both tests at 15/16 taps (CT15/16) about 16" deep and 20/21 taps (CT23) at the interface between the old snow and the newest snow (about 28-30" deep). We then conducted an extended column test and had a minor failure at 17 taps (ECTX17) and then a full propagation at 25 taps on the new/old snow interface at 30" deep (ECTP 25). We were actually expecting scarier results with the faceted snow that we were seeing but we are still not ready to jump on anything steep.
