Marker size: 18" x 28"

The discovery of Oil in Ector County December 28, 1926, marked the beginning of a new economic era for this region.

The first Well, " J.S. Cosden No.1-A W.E. Connell ", was named for the driller and owner of land. Its meager initial output of 38 barrels per day did not cause much excitement, but experts insisted that vast oil deposits lay under area (permian basin).

In 1929, Robert Penn's Gusher catapulted Odessa to boom-town fame. Oil has sustained the area economy since then, although the discovery Well was pugged and abandoned in 1940.

Ector County, Texas, has a rich history that dates back to prehistoric times. The area was once inhabited by various Native American tribes, including the Comanche, Apache, and Tigua tribes. Spanish explorers arrived in the region in the 16th century, but it wasn't until the mid-19th century that permanent settlements began to form in the area.

The county's history took a major turn in 1881 when the Texas and Pacific Railway reached the area. This led to the establishment of the town of Odessa, which would later become the county seat. The area experienced a boom in population and economic growth, thanks to the development of the railroad and the discovery of oil in the early 20th century.

The county's economy became heavily reliant on oil, with many residents working in the oil fields or related industries.
