Sierra Nevada Porcupine?

A place to explore the natural setting (geology, flora & fauna), people, constructed infrastructure and historical events that play and have played a part in shaping the Sierra Nevada as we know it today.

I think the video is probably better than any of the pictures I have. But I took a screen cap from it kinda showing the varmint from the side.

Well after looking at the second photo, my considered opinion is that I'm no wildlife biologist and I have no clue what
I'm looking at. :nod:

I'm no wildlife biologist, either, but I have photographed about a bazillion yellow bellied marmots and hoary marmots over the last forty years. Throw in a few porcupines and badgers. In the photo above, that animal has a marmot tail, and its walk is like a marmot. I was thinking about the unusual dark streaking, and I thought maybe it had gotten into some wood ash from a fire.

Most marmots I see are quite a bit darker brown overall. Could this be a senior citizen marmot whose coat has just gone a different color?

I think the answer is yes. I've seen some pretty old yellow bellied marmots, and they tend to grow gray fur on top.

Hoary marmots, on the other hand, tend to be quite gray through their entire life.

Yeah, I was kind of wondering where the photo was taken.
Shadow lake inlet.
Ah, thanks. I should've known as I've been by there more times than I could possibly rationalize.

Wondering if it could be a porcupine with mange. The coloration looks a lot more like a porkie than a marmot, and the way it's moving suggests it's not particularly healthy. Mange isn't super-common in porcupines, but they sometimes get into rodent poison. If the poison doesn't kill them outright, it can tank their immune systems. Mange is one of the most common problems for any critter - bobcat, coyote, porcupine, even mountain lion - walking around with rodent poison in its bloodstream. And it's a widespread problem in even fairly remote parts of the Sierra Nevada.
