From Fort Stevens Historical Site & Military Museum parking lot ($5 day use fee), walk across the yard in an easterly direction. Actually, you can walk back on the road you came in on. Soon your coordinated machine will point off to your left. Go that way until your handy-dandy machine again points to your left. Now go that way until you see the “Mine Loading Building” (32). At the “Mine Loading Building” go east until you come to N 46 12.393 W 123 57.263. Head north following your machine to GZ.
