Remote trigger or natural

Riding cougar creek E today, we either remote triggerd or a natural size 2 happend about half way down on the riders right. Great snow today, cougar creek still needs a bit more to fill in, lots of flag trees.

Came over a Crest to see a size 2 that had recently popped, not sure if we remote triggerd or it was natural from this morning, it started on a ridge where the crust went thin to thick. 50cm deep ran about 200m, 50m wide
