Tuesday encountered medium and smaller surface hoar ~12 miles WNW of that location... found on most aspects near and below... however I noted that by the end of the day, most aspects below treeline...

1 deep pit from yesterday for what little it is worth as a single data point...

below treeline, just below 11K NE facing, very open trees ~30deg, ~2mi N of two elk pass

250-220 F
220-165 4F...
