In the open plains surrounding the mesa rim (6,000 feet above the sea), are seen broad stretches of dusty sage brush and prickly greasewood. Where the plain rises toward the base of the mesa a scattered growth of scrub cedar and piñon begins to appear. But little of this latter growth is seen in the immediate vicinity of the villages; it is, however, the characteristic vegetation of the mesas, while, in still higher altitudes, toward the San Juan, open forests of timber are met with. This latter country seems scarcely to have come within the ancient builder’s province; possibly on account of its coldness in winter and for the reason that it is open to the incursions of warlike hunting tribes. Sage brush and greasewood grow abundantly near the villages, and these curious gnarled and twisted shrubs furnish the principal fuel of the Tusayan. Occasionally grassy levels are seen that for a few weeks in early summer are richly carpeted with multitudes of delicate wild flowers. The beauty of these patches of gleaming color is enhanced by contrast with the forbidding and rugged character of the surroundings; but in a very short time these blossoms disappear from the arid and parched desert that they have temporarily beautified. These beds of bloom are not seen in the immediate vicinity of the present villages, but are unexpectedly met with in portions of the neighboring mesas and canyons. After crossing the 6 or 7 miles of comparatively level country that intervenes between the mouth of Keam’s Canyon and the first of the occupied mesas, the toilsome ascent begins; at first through slopes and dunes and then over masses of broken talus, as the summit of the mesa is gradually approached. Near the top the road is flanked on one side by a very abrupt descent of broken slopes, and on the other by a precipitous rocky wall that rises 30 or 40 feet above. The road reaches the brink of the promontory by a sharp rise at a point close to the village of Hano. METHODS OF SURVEY.
