This marten was likely up at 10,900ft/3300m to hunt pikas, but when I stumbled along it became very curious about me. I was able to snap photos for about 8 minutes, then moved on to photograph the flock of rosy finches that was half dosing off while observing the marten. I wasn't able to observe any predation, but may have heard a couple distant screams.

I found a black widow under a log the other day. I offered her a cup of coffee and asked her how she liked her insects, but she just gave me a venomous stare and scurried away. I guess she wasn't in the mood for small talk

Colony was on large boulder beside river with other colonies. Might have been at the high water mark as there was silt remains on the boulder.
