SPANISH FORK — National Forest fire crews suspect that a blaze that spread through three piles of debris caught fire Saturday up Salt Creek were caused by man — although they're uncertain if it was intentional or accidental.

Robert Tonioli, assistant fire management office for Uinta Wasatch Cache National Forests, said the fire started earlier Saturday and spread to three piles of forest debris. Tonioli said the cause is probably man-made, and it has burned about two acres of land.

Forest Service crews have contained the blaze, and Tonioli estimates it will burn out by early Sunday morning.
