A gallery highlight is the prize-winning collection of three-dimensional petrified wood pictures of ghost towns and houses and barns reminiscent of the Great Depression era of the 1930s. The collection has won prizes at gem and mineral shows throughout the nation. at one event in St. Louis, Missouri, the exhibit won both top awards, one judged by the general public and the other by exhibitors - the first time in the history of the show that both awards went to the same exhibit.

Also popular with gallery visitors are pictures of birds made with naturally colored pieces of petrified wood. There are baby robins, chickadee, woodpeckers, owls and eagles.

Visitors will find a unique collection of lapidary art, including beautifully polished rounds of wood, limbs, agates, spheres, and carving artistically displayed. There are also fossil cones and fossilized leaf imprints, as well as Native American artifacts, which were formed within a 25-mile radius of Ogallala, mostly in the Lake McConaughy area.
