I have a geology obsessed kid. She loves rocks, geodes, crystals and dirt!

This is someplace you'd want to go when it's warmer, and it's in Central Washington, but Stonerose is a wonderful place for hunting fossils. Nice campgrounds nearby if you make it a weekend trip! http://stonerosefossil.org
I live in beautiful northeastern WA and would love to get ideas where I can rock hound and find something cool. Please nothing in or south of Spokane. ;) Thank you! (I live in Chewelah)
