Sphinx offers 20+ acre lots with access to the Madison River through a strip of BLM land, spectacular views & wide open spaces. They are the least expensive 20-acre parcels in the Madison Valley. There is no HOA at this time but could be set up by property owners in the future. All lots will require wells & septic systems, with well depths in the area ranging from 96' to 370'. There is now fiber optic cable to every lot in Sphinx. Covenants require 1,200 SF of living space, no modular/mfg. homes & no more than 7 acres may be permanently fenced. Sphinx is strategically located in the middle of the Madison Valley with abundant access to hunting, fishing, snowmobiling, trail riding, hiking & exploring in the many mountains, rivers, lakes & public lands. Sphinx is just 15 miles south of Ennis & approx. 1-1/2 hours to the Bozeman airport & to Yellowstone National Park. Lot 40 is on lower level, below the bench and the irrigation canal. It is unlikely power will be brought to this lot.
