True Granite- another cool erratic in Lake Stevens

The True Granite erratic is on NE 99th Avenue SE in Lake Stevens, Washington. Click to enlarge.

Craig Valvick and Matt McCourt told me about another erratic in Lake Stevens. This one is interesting and different because it is a true granite, with big pink orthoclase crystals and smoky-gray quartz. I call it the True Granite Erratic, and you can read about it, and the difference between granite and other granitic rocks such as granodiorite.
