This is the second installment of a series discussing how the ice age affected the North Okanogan and eastern Washington state. The first installment can be seen here.

Our first wandering boulder can be found alongside Havillah Road 6.1 miles northeast of Tonasket, according to Google Maps. This is a really big rock and it’s just sitting out in the middle of nothing right where it was dropped from its ice sheet. I’ve included GPS coordinates so you can fly over it with Google Earth.

And if you’re in the area and are hoping to visit the site then just follow the map from the town of Tonasket on Hwy 97. Please – at all times respect the private property of the families on whose land these and other natural interests live.

I don’t know of an official name for this big guy, but it is really a splendid thing to see. I need to consult with local experts to verify it is an erratic and to discover any history that may be known about it. There’s another just a short distance to the south across the roadway and I’ll be presenting that later. Here is me stepping over snakes and other imagined beasties as I approach our first erratic in the wild.

Update: Somehow this seems too easy, but the name for the adjacent spur road is Split Rock Road which leads me to conclude the rock’s name is, um…, Split Rock.
