McMinnville, OR

The largest glacial erratic (rock of different type than local rock, transported to current site by glacier or ice floe in a large, glacier-dammed lake) in the Willamette Valley in western Oregon. So out-of-place on a hilltop near McMinnville that it was granted its own state park. With a picnic table. The approx. 5m long by 2m high rock is reached via a path thru a vineyard. Great views of the Cascade Mountains from the rock (on a clear day). On our visit, it even came with a cuddling young couple for scale.
