What in the world caused these spikes?
Does this travels down?

Conclusion Snow conducts temperature bi-directionally Really? Bi-directional only? Light is a big influence to temperature Between the two pits
Ground sensors have very similar temperature patterns
Temperature from different pits will vary from depth, snow structure(history), pit location, light, etc…
Temperature data patterns at sensors that can see light is very different from those who don’t
