Fire managers are expecting to conduct a prescribed fire operation on the North Kaibab Ranger District this week. The Telephone Hill Unit is located approximately 14 miles south of Jacob Lake adjacent to State Route 67, which has closed for the winter season. Fire Managers are focusing ignition around the Pleasant Valley Cabin area of the unit to reduce hazardous fuel loads around the cabin and State Route 67 corridor, the operation is expected to affect about 700 acres in that vicinity.
