J.T. Murphy No 1 Crater, Historic crater site in Union County, United States.

J.T. Murphy No. 1 Crater is a 450-foot-wide, 50-foot-deep crater about 3 miles north and west of Norphlet, reached off Firetower Road roughly 3/4 mile north of Baugh Street. The main bowl is joined by several shallower craters, and the former cotton land around them has grown back into forest.

In 1922, a drilling accident triggered underground natural gas explosions that transformed formerly cultivated farmland into a substantial geological formation. The series of detonations left behind not only the main crater but also created multiple smaller pits throughout the surrounding terrain.

The name J.T. Murphy No. 1 comes from the well drilled there, completed on May 14, 1922, to a depth of 2,000 feet. The land had been in cotton production before the accident; it was abandoned and has gradually returned to forest. The site was listed on the National Register of Historic Places in 2008.

The site is reachable via Firetower Road, located about a mile north of its intersection with Baugh Street near Norphlet. Visitors should expect uneven forest terrain and plan for sturdy footwear, as ground conditions vary with the seasons.

Multiple underground explosions created not only the main crater but also formed several smaller satellite craters throughout the surrounding area.
