Mt. Blackmore Snowpit

Mt. Blackmore Snowpit

This snowpit shows a faceted layer just under an ice crust about 2ft deep.  It is not a major concern as it does not have enough stress from recent snow to produce widespread avalanches.  However, its ability to propagate fractures (ECTP) is a red flag that tells us human triggered avalanches are definitely possible.  Check the videos from Feb 17th and Feb 6th.
