For Fathers Day, my kids got me a book that I’ve had my eye on for awhile — Iowa Underground: A Guide to the State’s Subterranean Treasures. I first encountered it a number of years ago on Google books, and then it appeared on the shelves of a local big-box bookstore.

Written by Greg Brick, a Minnesota geology professor, the tome highlights several caves on public lands, complete with history, gear recommendations and directions. It has a few of my favorite haunts, a lot of locations I knew about but have yet to explore and even a few new caverns.

In the spirit of Fathers Day, I plan to use the book to inspire my kids to go off on adventures.
