A great adventure set somewhere in the West. The boys are invited by Cap, their high school track coach, to accompany him to Wildcat Swamp to dig for fossils. Naturally a mystery involving a secret at that same swamp adds to the adventure. I really enjoyed this one. ( )

I did not love this book. In part I struggled to imagine the scenery in my head. Hardy Boys would climb mountains and other rugged areas and I could not picture the area that they were in. I did not think of quitting due to the topics of fossils and trains. I am glad I held on. The second half of the book was much better.
The bad guys in this book are the worst that they Hardy Boys have encountered. It was like watching a chess match between the Hardy Boys and the bad guys.

If you like trains and fossils, you will enjoy this book. ( )

Very good condition, original cover
