The Churchill National Park is a national park located in the Greater Melbourne region of Victoria, Australia. The 271-hectare national park is situated 31 kilometres southeast of Melbourne. An old quarry is located in the north west corner of the park, remains of the associated tramway and crusher foundations are still visible. The tramway was known as the Scoresby Tramway.
The tramway was used to transport crushed rock from the quarry, it was constructed by the Dandenong Shire Council in 1912. The wagons travelled by gravity for most of the distance, when the topography leveled out, horses were used to draw the waggons. The quarry operated for approximately three years, the tramway was removed after the cessation of quarrying.
The cache is 10 meters downhill from the tramway remains, in a 250ml "lunchbox"
