Vane of the Timberlands by Harold Bindloss

The weather was not the only thing that troubled Vane as he stumbled on through the mist. Any unathletic tourist from the cities could have gone up without much difficulty by the way they had ascended, but it was different coming down on the opposite side of the mountain. There, their route led across banks of sharp-pointed stones that rested lightly on the steep slope, interspersed with outcropping rocks which were growing dangerously slippery, and a wilderness of crags pierced by three great radiating chasms lay beneath.

After half an hour's arduous scramble, he decided that they must be close upon the top of the last rift, and he stood still for a minute looking about him. The mist was now so thick that he could see scarcely thirty yards ahead, but the way it drove past him indicated that it was blowing up a hollow. On one hand a rampart of hillside loomed dimly out of it; in front there was a dark patch that looked like the face of a dripping rock; and between that and the hill a boggy stretch of grass ran back into the vapor. Vane glanced at his companion with some concern. Her skirt was heavy with moisture and the rain dripped from the brim of her hat, but she smiled at him reassuringly.
