The owner does have a little pricey gift shop, but about 20 feet across the parking lot he has a whole huge rock shop building. Outside he has crates and crates that you can look through to see what you want to buy. He will sell it to you by the pound or he will just give an estimate. I brought 12 rocks up to him and he said i can have them for $8. Three of them were petrified wood, two others were agates, the others just cool rocks. We spent an hour just pouring through the crates to see what we wanted to buy! We were here in August 09.
This area is one of the Black Hills' largest natural exposures of petrified wood, dating from 120 million years ago. The self-guiding tour includes a :20 animated videotape describing the historical geology of the Black Hills and tree petrifaction, digital audio and graphic museum displays. We were given a map with 20 marking and followed a five-block trail that passes logs ranging from 5 to 100 feet long and up to 3 feet thick. Allow 1 hour minimum. Honestly, the photo's don't look too exciting. A path with marked logs ... The gift shop contained a lot of kitsch. The rock shop was filled with rocks & petrified wood; it was a bit pricey.
