A brush fire that erupted Monday just north of Prado Dam, alongside the Corona (71) Expressway, scorched roughly two acres before crews from multiple agencies stopped it.
The non-injury blaze was reported about 12:10 p.m. in the area of the 71 and South Euclid Avenue, bordering the boundary between Riverside and San Bernardino counties, according to the Riverside County Fire Department.
The agency said that crews from the county, San Bernardino County Fire Department and Corona Fire Department reached the area within minutes and encountered flames in heavy vegetation, moving slowly to the east.
A Cal Fire water-dropping helicopter was summoned to make runs on the brusher, which did not threaten any homes or other structures, but did prompt the California Highway Patrol to partially close the Euclid exit ramp from the 71, as well as implement lane closures on Euclid, for public safety.
By 1:50 p.m., firefighters had established tentative containment lines, and most Riverside County crews were clearing the area, according to reports from the scene.
There was no immediate word on how the blaze started.
