Fabulous acreage in Gilpin County, you will love this lot! Gilpin County does not add an address until a home is built on the land, so use the Pin to find the lot in pubic records. 19.5 acres, not sure why the legal description says less, the buyer needs to verify. The legal description is: S:33 T:1S R:72W parcel of land in SW 1/4 of NE 1/4 DESC 298/401
