rooms. The members of the clan no doubt lived in these rooms and the men held their ceremonies in the adjoining kiva. Two of the kivas in Spruce Tree House have side entrances that lead to nearby rooms. These rooms may have been the homes of the priests, or dressing rooms for them.

DATE OF OCCUPATION

Twenty-one of the roof beams in Spruce Tree House have been dated by tree-ring chronology. These dates show that the houses were constructed during the years between 1230 A. D. and 1274 A. D. In 1276 A. D. a 23-year period of drought began that caused the cliff dwellers to move to regions where there was a more permanent supply of water. In those same regions are the homes of the modern Pueblo Indians and no doubt some of these people are the descendants of the Cliff Dwellers.

CLIFF PALACE

Cliff Palace lies in an eastern spur of Cliff Canyon under the roof of an enormous cave that arches 50 to 100 feet above it. The floor of the cave is elevated about 200 feet above the bottom of the canyon and is just under the rim of the mesa. The entrance of the cave faces west, toward a great promontory upon which stands Sun Temple.

The total length of the cave is over 300 feet and its greatest depth is just under 100 feet. The vaulted roof is so high that the cave was always light and airy and offered a perfect home site to the cliff dwellers who were seeking protection from the elements as well as from their enemies.

Fortunately, the configuration of the cliffs above the ruin makes it possible to get a fine birdseye view from the rim of the mesa. Views obtained from the heads of the two trails are most striking and give an idea of the setting and size of the building before it is entered for closer inspection. The most spectacular view of Cliff Palace is from Sun Temple, across the canyon. This is the only spot from which the entire ruin may be seen.

LIVING ROOMS

Cliff Palace is the largest known cliff dwelling. Dr. Fewkes, who excavated the ruin in 1909, placed the number of living rooms at slightly more than 200. Very few of the walls reached the top of the cave because of its great height, but many of the structures were as high as two and three stories. Near the south end of the ruin is the tallest structure, a four-story tower that reaches the cave roof. Ground space appropriate for building purposes was at a premium in the cave. To provide for an increasing population, second, third, and even fourth-story rooms were superimposed on the original single-story structures which predominated in the initial cliff-dweller occupation of this site.

When the cliff dwellers started building in the cave they were confronted with the problem of an uneven floor. The floor of the cave slanted from the back to the front and was covered with huge, angular boulders that had fallen from the cave roof. This problem the cliff dweller solved by erecting terraces and filling in the irregular places. The open spaces between the boulders were excellent for kivas, as there was not a great deal of excavation necessary. After the kiva walls were built the extra space was filled in with trash and dirt. When the flat kiva roof was added a level court resulted. Around this court the homes were constructed, often on the rough surfaces of the big boulders. Because of the uneven floor and the terracing that was necessary, six distinct terrace levels resulted.

KIVAS

Twenty-two kivas are located in the cave and another, lying about 50 feet from the western end, and thought to have been used by men living in the cave, brings the total to 23. Twenty of these conform to the plan of the typical Mesa Verde kiva, but three seem to be of a different type. These three, instead of being round, are square with rounded corners. The banquette is missing as well as the pilasters or roof supports.

STORAGE ROOMS

Because of the fact that the inhabitants of Cliff Palace were forced to store enough corn each fall to last until the next harvest a great many storage rooms were constructed. Any small nook or cranny that was too small for a home was utilized for that purpose. Far back in the cave a number were constructed of large, thin sandstone slabs. These slabs were placed on end to form small rectangular rooms, and when the door slabs were in place and all of the crevices were well chinked with mud the grain was safe from the rodents. High up under the roof of the cave, at the back, was a long narrow shelf that was also utilized for storage space. A wall was built along the front of the ledge, closing it up completely, and the space back of the wall was divided into 14 small storage rooms. A ladder on the roof of one of the houses below gave access to the ledge.

PAINTINGS

In the third floor room of the four-story tower is the finest painting yet found in the Mesa Verde. The entire inner surface of the four walls was covered with bright red designs on a white background. The designs are similar to those found on cliff-dweller pottery. The white color was obtained by mixing finely ground gypsum with water to form a smooth paste; the red was obtained by treating hematite, or red ochre, in the same manner.

THE ROUND TOWER

The outstanding structure in Cliff Palace is the two-story round tower that stands just south of the center of the cave. Every stone in this tower is rounded to conform to the curvature of the walls and the graceful taper toward the top makes it one of the finest examples of masonry work in the region. When the early explorers first entered this tower the only object found was the most beautiful stone ax they ever discovered. Whether this tower was a home or whether it was constructed for some special purpose can only be conjectured.

POSSIBLE POPULATION

Because of the fact that Cliff Palace is the largest of all cliff dwellings, its population is of special interest. A close inspection of the rooms in the ruin shows that they are smaller, on the average, than the rooms in any of the other large cliff dwellings. When judged from our modern standards, it is difficult to imagine more than a couple of people living in each one. Our modern ideas, however, will not help us in understanding the people who once lived in Cliff Palace.

More than anything else the cliff dwellers desired security from their enemies. Their next desire was safety from the elements. When it is considered that these were the motivating influences, it can easily be understood that such minor matters as space and comfort would receive little consideration. Since the inhabitants were an easy-going, peace-loving group it can be imagined that crowded living conditions would not be objectionable. In addition it must be considered that the rooms were used principally as sleeping quarters. All activities were carried on in the open courts and on the terraced roof tops. Even the cooking was done over open fires outside the houses.

An average of two to the room would give a population of 400; an average of three would place 600 in the cave. If every room were occupied at one time and if the average of two or three to the room is not too high, it would seem that a total population of 500 would not be too great for Cliff Palace.

BALCONY HOUSE

Balcony House lies in Soda Canyon about 2½ miles southeast of Spruce Tree Camp, and is reached by a continuation of the Cliff Palace Road. It is one of the most picturesque of the accessible ruins in the park and occupies a better position for defense than most of the other ruins on the mesa. A few defenders could have repelled a numerous attacking force. Additional precautions have been taken at the south end of the ruin for the strengthening of its defenses, where the only means of reaching it is through a very narrow cleft. The south
