Officials have stopped short of calling them arson related, but admit it's becoming suspicious.

Thursday, fire crews responded to another fire in Zintel Canyon in Kennewick, this one burned from near the 2200 block of East Dennis Street. It began near the top of the East Bank of the canyon, then traveled to the trail below.

This is the fourth such blaze since August 30, but the third one reported since last weekend. Anyone with any information is urged to call (509)-628-0333, and police are asking residents and those who hike the trail to keep a close eye out.

Our region is still pretty dry, but a little rain and cooler temps have dropped the number of fires virtually everywhere except in the canyon, which is why it's very suspicious.
