SHIPROCK — A 20-acre wildfire west of Shiprock was contained Monday afternoon, roughly three hours after it started.

The fire started about three miles west of Shiprock on Mesa Farm Road and spread southwest along the San Juan River.

A total of 15 engines from Farmington, San Juan County, the Bureau of Land Management's Farmington Field Office and the Bureau of Indian Affairs were called to the area to battle the blaze.

The fire started around 3 p.m., and the BIA took control of the charred area for clean up by about 6 p.m.

"The cause is currently under investigation," said San Juan County Division Chief David Vega. "But it was most likely human-caused."

The fire primarily burned along the San Juan River bottom, fueled by the area's salt cedar shrub plants, Vega said.

No injuries were reported.
