1976 Knox ranch was purchased by Bud Hoff of Hoff Lumber Co. from Ramona Reineke.
1978 Knox ranch was traded to the USFS for other land by Hoff Lumber Co. (Genealogical Library notes). Knox went through three broad historical phases. First was the initial settlement by miners and transients. Second the historical establishment of a homestead and development as a town serving the travelers to the Thunder Mountain and Roosevelt area. Third was the decline due to improvements on road travel, decreased mining, and growth of tourism in the area. From Carolee Fogg’s senior seminar paper on Knox Ranch, 2000.

1982 the Corps of Engineers had a fish trap built on the South Fork of the Salmon River to trap Chinook salmon. It is downstream from the Warm Lake highway bridge on the South Fork around one mile. To reach the fish trap from the South Fork bridge go ¼ mile toward Cascade on the Warm Lake Highway and turn right on the gravel road to the Two-bit and Six-bit Road and go 0.9 mile to a steel gate on the right side of the road. Park off the road and hike about 1/3 mile down to the trap facilities. The Idaho Fish & Game collect fish in the trap during the July to Sept. run. Fish eggs are harvested for hatchery raising from the native fish stock and then the smolt are placed back in the river 1.5 years later. Meyer notes
