Lester and Haltom No. 1 Well Site is located in Arkansas

The Lester and Haltom No. 1 Well Site is the site of the first discovery of oil in the state of Arkansas in 1920. It is located in Ouachita County, about four miles (6.4 km) east of Stephens, and off Old Wire Road (County Road 3). The site is overgrown, with limited evidence of its past. There are (or were, in 1976), two large depressions in the ground, about 2 ⁄₂ to 3 feet (0.76 to 0.91 m) deep, and up to 75 feet (23 m) long and 35 feet (11 m) wide, one used as a mud pit, the other as a slush pit. A tar-blackened trail shows where there was runoff from the well, whose drill hole was just to the south of the mud pit. East of the mud pit is another depression where the steam engine was mounted; there is still a turnbuckle embedded in a nearby tree.^[2]
