Lost Valley

the long version

"Lost Valley Ranch is a far-reaching land empire founded by James Hyland, advanced by his son, and inherited in the third generation by Douglas Hyland. In the town adjacent to this mighty ranch, Sheriff Evan Hatfield, a fair-minded man, maintains the peace. Then a homesteader arrives whose claim, issued by the Denver Land Office, was on the Lost Valley range. As Douglas travels to correct the error, new claimants arrive - and nothing is going to stop them."--Publisher's description.
