Multiple Whumps between Red Lake and Lost Lakes

Went for a tour from Red Lake towards Lost Lakes. Stayed in and below treeline and out of avalanche terrain given the moderate forecast and the fact that I was traveling alone. Heard whumps on eastern facing aspects at least 5-6 times, all occurring on mellow slope angles (less than 30 degrees). Dug the first pit (pictures 1-3) on an eastern 26-degree slope and the second pit (picture 4) on a North to Northwest aspect 27-degree slope. The other pictures (5-6) are of some of the snow from the Dec 11th facet layer that is possibly showing some signs of cohesion. Finally, the last picture shows an eastern facing slope that had what appeared to be a small dry loose avalanche towards the very top if you zoom in closely. Forgot to bring my snow saw so did not get to complete any compression tests. Apologizes for the sub-par snow pits, I'm relatively new to it.
