Smoldering stumps, roots, or snags can hold heat in the aftermath of an incident like the Riverside fire.

Holdover smoke from the Riverside Fire could be seen from Estacada last night.

On Monday, June 28, the Mt. Hood National Forest announced on social media that the smoke was from last fall's 140,000 acre Riverside Fire and not a new incident.

"Holdover fires can crop up in smoldering stumps, roots, or snags that have been holding heat. In summer and fall, they dry out and start putting out smoke. n the Riverside Fire area, these holdover fires are most likely to occur in very remote areas in the interior of the burned area and unlikely to spread," a Facebook post stated.

Forest Service leaders are monitoring the areas and have plans in place if there is a change in the situation.

Last September, the Riverside Fire began on the Mt. Hood National Forest and came within a half-mile of Estacada city limits. The incident reached 100% containment Friday, Dec. 4.

There were no fatalities from the Riverside and nearby Dowty Road fires, but 150 structures in the Estacada area were lost — including 50 homes. Sections of the Mt. Hood National Forest remain closed as officials clear debris and ensure the area's safety.
