The parking area shown on the Minnesota DNR Web page for this site is inaccessible by car. It is at the end of a DNR public road. However, there are two gates across this road. The first is at the start of the road near the intersection of Township Road 184 (170th St.) and 150th Ave. On two recent trips (August, 2013 and August, 2016) the gate was unlocked. On two previous trips (August and September, 2011) the gate was locked. The second gate is 0.7 mile east on the DNR road. During four visits to the SNA over five years this gate has never been unlocked.

If the first gate is locked, park on the south side of the DNR road near the gate, being careful to avoid blocking the gate. Hike east on the two-track road one mile to the SNA boundary marker.

First Gate
N47 23.881, W95 57.287

If the first gate is unlocked, drive east on the DNR road ½ mile to the Wambach WMA parking lot. Park here and walk ½ mile east to the SNA boundary marker.

The wood sign for this SNA is at the east boundary bordering 170th Ave. There is no parking area near this sign.
