We suspect that heavy rains have made this layer less of an issue in many lower elevation areas.  However, we KNOW this layer is still preserved in many tree line and below tree line locations which were not as affected by high freezing levels and rain events.  In other words, if there is no THICK rain crust at and below tree line, be on the look out for buried surface hoar.  Importantly, buried surface hoar is more preserved in the North and in some places a thin rain /temperature crust caps intact crystals.

Its distribution and extent remains unclear - especially in the Northern regions - but we believe it is widespread in the southwestern portions of the region with reports of up 1- 5cm thick near tree line.  In some areas there are two rain crusts: a thin crust near the base of the recent storm snow and a second thicker crust near the surface.  See this MIN report from near Crowfoot Mountain & this MIN report from the South Columbia near Hall Mountain.
