Small windslab slide near Roundtop, 3/4/19

I know this is already obsolete, but anyway... toured out to Roundtop on Mon 3/4.  Very windy in AM, but calmed down around noon.  Saw evidence of a rider-triggered small slab slide above a windloaded rollover, at about 9k on NE aspect, this is in the area of steeps kinda NW of Winemucca lake above the drainage going down to Woods Lake.  Crown was about 1 ft.  There was lots of evidence of wind up there and that particular area seems especially exposed to it.  That said, this was the only instability I actually experienced that day, somewhat surprisingly.  This was after riding excellent stable pow in Crescent couloir on Roundtop, and carveable windboard in the bowl below it.

Some pics:

This is from the skin out earlier in the day, from the NW end of Winemucca Lake.  Area in question is middle of the left side of the pic, at the rollover below the sparse trees.

Later in the day (probably a couple hours after incident) view looking down above the rollover:

As I traversed over to mellower terrain I was right at the rollover, and another pocket slid out, maybe 10-20 ft wide, about 1 ft deep.
