Blue Lake Rhino in the Coulee Corridor

As you continue south on Highway 17 from Sun Lakes State Park, through the majestic Lower Grand Coulee, you will come to a small, unassuming, resort called Laurent's Sun Village Resort. You can rent rowboats at this resort and the most remarkable thing is that just across the lake there is a small cave that was actually formed by the body of a prehistoric rhinoceros that was caught up in a lava flood when all this basalt rock was laid down during late Miocene and early Pliocene times (between 17 and 6 million years ago). Be sure to bring a flashlight and be ready to crawl into the tight cave.

If spelunking in small caves isn't your cup of tea, I suggest renting the rowboat, check out the cave from the outside and then take the kids over to Seattle to the Burke Museum where they have made a full size mock up of the cave from plaster casts and have a nice educational display about it. Laurent's also has a miniature golf course, park, camping, cabins, and fishing opportunities. To learn more about the lava floods check out the USGS website.
