Open FREE to the public. Weapons display, old west buggies, fossils, native American artifacts, vintage clothing, coal industry information, and tons of history of the City of Gillette are all located in this amazing place. Some things are hands-on and have a picture of hands to let you know. Some things are not as this is a museum after all. Small souvenir area with postcards, coal candy, Wyoming found jade made into jewelry, fans, bonnets, glass bottle soda, and more. Remember that every $ you spend there helps keep this FREE museum's lights on. Also a fun spot to take a silly picture for 2 near the entrance. There is also a guest log you can sign when you enter. Brochures near the front that give you other touristy things to do in the area while here. My family had an amazing time here despite not getting to see the whole other building (cranky baby needed food and a nap).
