Pierre's Hole, as it
was then called, or Teton Basin, its present name, is one of those valleys which
are veritable oasis in the desert of rugged mountains. Very few of these valleys
exceed that of Pierre's Hole in beauty. It is overhung on the east by that noble
range of mountains whose culminating peak is the
Grand Teton. The valley extends in a direction from southeast to northwest.
It is fully thirty miles long and from five to fifteen miles wide. It appears
like a broad, flat prairie almost destitute of trees except along its principal
river and the various tributaries.
