(Old) Dumps and Incinerators, Pits, Quarries

For many years, the park dumped all of the garbage it generated into one or more of a handful of dumps that existed within the park’s boundaries.  The two largest ones were at Rabbit Creek on the west side and Trout Creek on the east side.  There were also dumps outside park boundaries at the North (Stephens Creek, closed in 1970), Northeast (Cooke City, closed in 1969), and West (north of West Yellowstone, closed in 1971) entrances, along with small dumps at Tower Junction (closed in 1968), west of West Thumb Junction (also closed in 1968), and at the South Entrance. In 1970, the Rabbit Creek Dump was closed and a new landfill established along Nez Perce Creek.  In 1970, the park closed the Trout Creek Dump as well.  There are known old dump sites located at Mt. Everts and along Dunraven Pass as well.

The park burns a considerable amount of refuse in incinerators located at Mammoth (lower housing area), Canyon (at the governmental corrals), Lake, and Grant Village.   Today, all garbage is shipped out of the park via truck.

There are a variety of landfills still used to dispose of excavated earthen material and non-hazardous construction debris.  Examples include the Mesa Pit, located off Mesa Road south of Madison Junction (east off the Grand Loop Road), the Frog Rock Pit (6 miles east of Mammoth), the Sylvan Pass Pit (located adjacent to the East Entrance Road near Sylvan Pass), and the old Canyon ball field and the abandoned Canyon Cistern.

There are also gravel pits used to provide road bed and raw construction materials throughout the park, including the one along the West Entrance Road, as well as a variety of staging areas used to stage materials used in construction (the Grebe Lake pit, for example).  A number of old quarries have been reclaimed, including pits at Little Thumb, Dry Creek, Ice Lake, the Natural Bridge Quarry, and the Lone Star Geyser and Sedge Creek pits.
