We took the trailer to Joshua Tree National Park this week, and camped at Black Canyon Campground. The campground is a really nice one - isolated from the town of Yucca Valley but close enough if you need to go into town for supplies. There are lots of roomy sites that are big enough for trailers and RVs, including 6 nice pull-throughs in the middle. We decided to try as many little hikes as we could to get some good exercise and to see the variety of sights in JTNP.
Our first hike was the nature trail at Indian Cove, which is surrounded by mountains made of granite boulders.
We saw quite a few of these odd features, and it was only after we stopped and looked closely that we saw thousands of ants coming to and from the center holes. We learned at the visitor center that the ants drag seeds down into the hole, and then take the empty husks back outside, making the mounds.
