Quarry Tours

Tours of the Thornton Quarry take place on the first Saturday of June and October. All guests must be 18 years old. Tickets are $30.00 per person. Proceeds benefit the Thornton Historical Society.


You may request reservations for the tour at anytime by contacting quarrytourthorntonhs@gmail.com. Please send your name, home address, phone number and e-mail address as well as how many tickets you would like. Reservations are kept on file by date received. First in, first out. At this time, we anticipate a one-year wait.


The north lobe of the quarry was sold but the rest of the quarry remains open and is expected to be in operation for another 75 years.

UPDATE: Our Quarry tours are sold out for 2023 and spring of 2024. We will have an updated Quarry booklet for sale as well as new designs for T-shirts.
