Sunday Lake Underground Rock Shop 202 Chicago Mine Road, Wakefield, MI 49968

"Great little place with a very knowledgeable owner. If you like rocks, this is a must-stop!"

"A hidden gem :) This place is packed full of amazing stuff. Carl, the owner, is also very knowledgeable about pretty much everything in his shop. I haven't seen better prices anywhere either. We stop in here every time we are in the UP and always find some awesome stuff. He also gave us tips on where to go locally to search for some of our own."

"We travel the country every summer and have never run across a rock shop like this one! The owner was so knowledgeable and more than happy to talk with us about the area and rocks. Highly recommend. We will be back!"

"This place was awesome! Exceptionally knowledgeable and friendly owner talked with me and my friend about rocks for over an hour! We were both very happy with our purchases and expanded knowledge. If you’re in the area make sure to take out some cash at the gas station ATM and head over to this incredible place!"

"Excellent rock shop! Karl was helpful and knowledgeable, and obviously passionate. I picked up this sweet Herkimer Diamond and several other treasures. He has a huge selection, lots of interesting things."
