Spruce Tree House, located in a large cave just across Spruce Tree Canyon from the museum, has been made readily accessible by a short winding trail. This is the only excavated cliff dwelling in the park that may be visited without going on a conducted tour, and is open to the public at all times. A ranger is always on duty to protect the ruin from vandalism and to give information to the visitors.
GENERAL DESCRIPTION
The total length of Spruce Tree House is 216 feet, and its greatest width is 89 feet. During the excavation of the ruin in 1907, Dr. Fewkes counted 8 ceremonial rooms, or kivas, and 114 rooms that had been used for living, storage, and other purposes. At least 14 seemed to have been storage and burial rooms so that probably not more than 100 were used as dwellings. If it is considered that a family occupied each room, the population would have been large, but it is doubtful if all of the rooms were occupied at one time. An average of 2 or 3 persons to the room, making a total of not more than 300 for the entire village, would no doubt be a fair estimate.
Two hundred feet north of Spruce Tree House the canyon comes to an abrupt box end. A splendid spring flows from the base of the sandstone cliff, and it was to this spring that the cliff-dweller women went for water carrying it back to their homes in their big water jars. At the south end of the cave a trail, consisting of small toeholds cut in the cliff, led to the mesa top above. This trail was used by the men as they went to their mesa-top fields, where they raised corn, beans, and squash, and by the hunters as they went in search of deer and mountain sheep that lived in the forests above.
LIVING ROOMS
The rooms of Spruce Tree House are divided into two groups by a court or street running from the front to the back of the cave, at a point just south of the center of the village. The majority of the rooms are north of this street, and some of the walls show the finest work in the entire structure. The stones were well shaped and smoothed; the mud mortar was carefully worked into the crevices and compressed with thin stone wedges. Over many of the walls was spread a thin coat of reddish plaster, often decorated with paintings. These rooms, standing as when they were constructed 700 years ago, are mute evidence of the cleverness of the masons who built them.
Spruce Tree House has more walls that reach the top of the cave than any other ruin in the park. All through the central part the walls were three stories high and the top of the cave served as the roof of the upper rooms. The first- and second-story rooms, however, had their own ceilings. Heavy rafters, running lengthwise of the rooms, were covered with a crosswise layer of small poles and withes, and these in turn were covered with a 3-inch layer of mud. Very often a small hatchway was left in one corner of the ceiling and a short ladder leaning in the corner of the lower room gave access to the room above.
Very few of the houses were equipped with fire pits. Most of the cooking was done in the open courts and the small fire pits can be found along the walls and in the corners of the courts and passageways.
CEREMONIAL ROOMS OR KIVAS
Spruce Tree House has eight of the circular, subterranean rooms that were set aside for ceremonial purposes. Similar rooms are still in use in the present day Pueblo Indian villages and are known as kivas.
