We just got back from a weekend overnight to Snowgrass Flats and Goat Lake in the Goat Rocks Wilderness/Gifford Pinchot Nat'l Park.
It was an amazing trip full of wildflowers, butterflies, mountain goats, and pika squeaks.
My hiking partner and I aren't very knowledgeable about wildflowers and didn't have a field guide with us... I was hoping you guys would be able to quickly ID a few flowers for us. The blooms up there right now are just lovely.
I hope these pictures work...
#1:

We called these the "muppet plants" because they looked like they might burst into head-bopping song at any moment!
#2:

I was guessing some type of alpine violet? Johnny jump-up, maybe? They were very small... dime-sized at MAX.
#3:

These purple guys liked to grow on ROCK, and would grow in big flat clumps all over the place.
#4:

Growing in the meadows and near the streams.
Finally, we saw these EVERYWHERE. As little internet sleuthing leads me to think they're pocket gopher tunnels, or "eskers"? Is this way off? One of the sites said that these are their tunnels that they dig under the snow during the winter? We saw lots of droppings that looked like they'd been "pushed" out of the end of the tunnels onto the trail in big clumps. The droppings looked like mouse or rodent variety.

Thanks for all your help!
