Unified Police canyon officers were dispatched to Millcreek Canyon Tuesday morning to aid a camper who had become too sick to hike out. A 911 call came in about 4:30 a.m. from the canyonâs Big Water Trail area, where a group of campers reported a 25-year-old male was passing out. The campers did not think he could hike back out without medical assistance. Unified Police Lt.
