Give I am no expert but it looks like a big hunk of dirty occluded quartz to me.

Agree w/ Madmox that its quartz. At 27 pounds that is quite a chunk!

It's not native to Iowa. Most likely moved there by a gracier. https://www.iihr.uiowa.edu/igs/erra...ing_wp_cron=1545618842.8057339191436767578125 Not sure what it is other than a granite of some kind?
