A distinct lack of trees in north-central Kansas led homesteaders to mark their boundaries with limestone fence posts.
Larry Rutter, who demonstrates post rock preparation, displays an antique hand drill used to bore holes into limestone slabs.
Damon Vonada shows a group of onlookers how his grandfather drilled holes in the post rock using the 1920s John Deere engine.
Fence corners need extra support. This post rock fence west of Hoisington, Kan., uses two additional leaning posts for reinforcement.

The late Albert Sayler taught Larry Rutter how to quarry post rock. Here, Salyer stands next to a slab of post rock north of Gorham, Kan., before it is broken out of the ground. Notice how the feathers and wedges align along the line to be split.
Damon demonstrates use of a different syle of antique hand drill than Larry uses to bore into the post rock.
