The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz.
Later in the Devonian, sea levels rose again, leading to the deposition of the Williams Canyon Limestone. During the subsequent Mississippian period, yet another incursion of the sea deposited the 350-million-year-old Leadville Limestone.
