The first walking tracks were constructed in 1939. Carbine's chute was the first of many trenches built to assist the removal of logs off the mountains. It can be accessed by a 1.5 km track from Munros camp. The last sawmill in the area was at Wengenville, which closed in 1961. In a successful attempt to reduce the splintering and damage to logs from falling down the steep trenches the owner of the Wengenville sawmill, Lars Anderson, used a combination of tramway, winches, winders and flying foxes to transport logs.
