Walk: Blue Gum Swamp Creek, Winmalee

P1050092This walk is both geological and botanical. When the Lapstone Structural Complex was created, its steep, east-facing monoclinal scarp was mirrored in more subdued fashion by a series of en-echelon west-facing faults. These caused temporary damming of creeks, and creation of wetlands like Burralow Swamp and Mountain Lagoon. In this era of late tectonic activity the Grose Fault rose and temporarily dammed Blue Gum Creek leading to a buildup of alluvium and the creation of a swampy, flat floored valley with high water tables. Mountain Blue Gums Eucalyptus deanei flourish in this environment creating a beautiful tall forest shading numerous flowering shrubs. Highlights are the forest of tall Mountain Blue Gums and a climb out from the valley to a lookout over the beautiful lower Grose Valley.
