This was one of several crawling over the large rocks by the Butterfly Meadow, and heading down to the leaf litter where they'll overwinter once it gets really cold, not emerging until spring. But once spring does come again, they'll be amongst the first insects out and about. You can see how similar this looks to the box elder bug in the next photo. But they are in fact, two different families. This one belongs to the Seed Bug Family, while the box elder bugs, are Scentless Plant Bugs.
