George William Moul was one of the earliest settlers in this area and homesteaded east of the falls in 1915. Under land pre-emption regulations, Moul was granted a war leave in 1918 and left the Clearwater Valley to serve in World War I. Moul returned to Canada after the war and settled in Vancouver where he worked for the
Canadian Pacific Railway. He died in 1947 and some of his relatives still live in Vancouver. Grouse Creek is the fourth name for the stream that forms Moul Falls. No other Wells Gray Park place name has been changed more times. Surveyor Robert Lee referred to it as Beaver Creek on his maps drawn in 1912 to 1914. After the area was settled, the stream became known as Grouse Creek because of the profusion of
blue grouse that inhabited these forests. The waterfall and creek were called Moul starting in the 1930s. In the 1980s, locals gradually reverted to using the Grouse Creek name, even though "Moul Creek" appeared on all the maps. The Ministry of Highways erected a "Grouse Creek" sign on the Clearwater Valley Road bridge in 1990 which confused travellers even more. The following year, the Friends of Wells Gray Park requested a ruling from the Geographical Names Office in Victoria. After an investigation of local and historical usage, a decision was announced in favour of Grouse Creek. Moul Falls remained unchanged. ==Access==
