The stars over Cornville are still out at five in the morning, and the cold slides down into the creek bottom near Page Springs and pools there until the sun clears House Mountain. Climb It High Tree Experts starts early because the tall cottonwoods are best climbed before the day gets any ideas — up on rope, working a crown down limb by limb, pruning out the dead wood and the crossing branches. Removals take the same approach, rigged and lowered in pieces when there is a shed or a row of vines under the drop zone. After a hard blow the calls come in for split trunks and hung limbs, and those are brought down and carried off. Coming out of a tree that has finally been put right is the reason for the whole day.
