6,000 ft is high country hunting, compared to where most hunters hunt. I saw 1 other hunter where we were, but saw a lot down low in the low lands. We had to ride motorcycles then hike in a long ways, no driving trucks for us, where you hunt you may have been able to access the higher elevation with a truck, not sure though but sounded like you shot it on a road. You see any mulies up there, seems like the area (high elevation) suits mule deer more than whitetailed deer.
Every year we shoot deer on the south facing slopes, the north facing slopes are heavily timbered, south facing slopes hold pockets of timber, but are fairly open with shale rock. I hunt south of Mount Stuart on the county line trail between Chelan county and kittitas county.
