Footprints on Snow

One of the neater things that happened in camp as time passed was watching the patterns of where the wind scoured the surface to produce blowing snow and where it deposited already blowing snow. Some places in camp, footprints would be covered with new snow within minutes given a nice breeze. There was always a fresh snow surface. But in other places where the surfaced was actively ablating, footprints could last through the entire season because our own body weight compacted the snow enough to resist the scouring action of the wind. The result: some really cool patterns of erosion around (and under) the footprints, followed by drifts accumulating on the lee side of footprint. Some examples:

It’s like a footprint graveyard out there.
