From Madison take 18/151 towards Dodgeville. At Dodgeville continue on 151 towards Platteville. You will make a right turn at the end of town in Belmont (still 151) and will be about 7 miles from Platteville. You will see the mound off to your right. About 4-5 miles after Belmont is Mound Rd. (maybe West Mound Rd.) At the base of the mound take a right and the farm with the access road is on your left. You go between the farm house and the out buildings up the access road to the top where the antennas are.
