According to the United States Census Bureau, the town has a total area of 0.75 square miles (1.93 km2), all land.

The cross is also 18 feet (5.5 m) shorter than the 208 ft (63 m) cross at the Mission Nombre de Dios in St. Augustine, Florida, and shorter than the 213-foot-tall (65 m) Lakeuden Risti cross-shaped church tower in Seinäjoki, Finland.

The leaning tower was originally a functioning water tower which was slated for demolition until Ralph Britten bought it and moved it to serve as a sign for his truck stop and tourist information center (located on a stretch of interstate that was once a part of U.S. Route 66).

This truck stop can still be seen, set back off the road behind the tower, now boarded up and in disrepair following a devastating fire decades ago.

[8] The leaning water tower still remains a popular target for cameras, and the town of Groom turns on a large colored star mounted on the top around Christmas time.

[10] The route from Fort Smith, Arkansas, to Santa Fe, New Mexico, along the Canadian River was charted circa 1849 by Captain Randolph Barnes Marcy.

Published in 1859, Marcy's book, The Prairie Traveler: A Handbook for Overland Expeditions, contained maps and illustrations of routes between the Mississippi and the Pacific and was used as a basic manual by westward-bound wagon trains and travelers for years.

Unfortunately, Groom's vision of the finest and most desirable cattle ranch in the United States did not materialize for him.

The bondholders foreclosed and organized a new company known as White Deer Lands (later White Deer Land Company), under the management of the agent Timothy Dwight Hobart, one of the subsequent founders of Pampa, Texas.

[11] The site of Groom was chosen in 1902, along the route of the Chicago, Rock Island and Gulf Railway.
