The shallow snowpack forms weak snow layers and when a snowstorm or wind deposits a new load on top of this weak snowpack, things move and avalanches occur," Supervisory Research Hydrologist at the Rocky Mountain Research Station Kelly Elder told KRDO.
The results are not a simple effect of firing rate normalization owing to our binning procedure: the size distributions are heavy-tailed, in the sense that large avalanches occur more frequently than would be observed for spike trains with identical mean firing rates but uncorrelated (see surrogated data in Figs. 3a, S3 and S4).
When traveling into avalanche country, carrying some simple equipment can save your life: Slope meter: Because avalanches occur almost exclusively on slopes between 25 and 50 degrees, and 90 percent of avalanches occur on slopes of 30-45 degrees, a slope meter is the single most important tool you can have to avoid avalanche danger.
