Earlier in the year, I visited Dolliver State Park up near Fort Dodge. It's a park similar to Ledges State Park in that it has sandstone bluffs. Dolliver's bluffs are composed of a slightly different mineral mixture than Ledges, called copperas. The park is pretty large and there are a lot of trails to explore.
It was kind of rainy when I went, so there were some snails out and about. Here's one that was hanging out on a tree trunk. He was pretty large. This is where the creek that flows through the park meets part of the road so you can walk right up to it. It wasn't very high that day but it rained a lot afterwards so it might have gotten higher after I left.
Here are some of the bluffs. There's a spot where you can get very close to the copperas and even see some petrified wood sticking out. It's very cool.
Another view of the creek further off one of the trails. This is near the spot where you can get close to the copperas bluff.
Walking past the bridge, you end up in this forest area. There are lots of little green shoots in the area. Apparently they have a very high silica content and were used by early pioneers to make broom bristles. They're very stiff and unyielding. I had never seen them before so this was very interesting to me.
