T Shaped Doors at Spruce Tree House

During the winter season at Mesa Verde National Park, Spruce Tree House is the only large alcove ruins site that can be visited. There are three free ranger guided tours per day leaving from the Chapin Mesa Museum at 10:00 AM, 1:00 PM and 3:30 PM.

One of the detail features of Spruce Tree House is the many T shaped doorways that are easily visible. T shaped doorways are particular to and symbolic of the American southwest. They are thought to have first appeared at Chaco Canyon, New Mexico around 1020 AD. The T shapes appear later at Aztec Ruins in Aztec New Mexico and then in the Mesa Verde area.

The left side plaza area behind the two reconstructed kivas has several T shapes visible including a few that appear to have been bricked in afterwards.

There is debate as to whether the T shapes have a practical function or are they symbolic. The wider top might provide a wider space for carrying material inside and places to place your hands if you want to vault into the room. The narrow bottom might help conserve heat.

Some have noticed that the T doorways are only present for habitation rooms and not for storage rooms. This would make the living rooms easier to spot from a distance. Most of the Spruce Tree House T shapes appear to be symmetrical, but this one has uneven shoulders and looks like a larger opening was bricked in later.

Another site in the Mesa Verde area with easy to visit T shaped doors is the Escalante Pueblo at the Anasazi Heritage Center in Dolores, Colorado. This site is thought to have been built originally in 1129 AD, making it older than Spruce Tree House where construction is thought to have occurred from 1200 to 1276 AD.

In this case the T shapes are lined up and lead from one room to the next and are not just on the exterior of the structure. Inside the Anasazi Center Museum there is a mug with a T shaped handle, giving support to the idea that the T shape is symbolic of something.

It looks like there are also places at Spruce Tree House where one T shaped door leads to another interior T shaped door. The winter tour of Spruce Tree House takes about 1:00 hour. On my mid December visit there were only two hikers on the 10:00 AM tour, a much better experience than during the busy summer season.

Mesa Verde Black on White Pottery

Hikers in the more remote areas of the Four Corners will frequently come across pottery shards near the ruins sites. Not many shards are visible at Mesa Verde, but the Chapin Mesa Museum has a good display of several styles including the Mesa Verde Black on White style.

The Anasazi Heritage Center in Dolores, Colorado has some textbook style explanations of different pottery styles and list more types of Black on White than the Mesa Verde Black on White. The definition of the Mesa Verde type given there says more common after 1200 AD. It has heavier designs with more black space, placed either in bands or in all-over patterns divided in halves, thirds, or quarters. Bowls are usually decorated on both surfaces.

The McElmo Black on White style is more common between 1150-1200 AD and often shows bands of triangles, checkerboards, steps, and hatched areas. Bowls were usually painted on the inside surface only.

The Chapin Mesa Museum doesn’t mention the different styles of Black on White but emphasizes the pottery forms. The description for this bowl says it has a ticked rim, a wide design band framed with thick and thin lines.

This water jar has a symmetrical geometric design with narrow spaced hatching. The water jars are also called Ollas. They may have an indentation on the underside to make it comfortable to carry on your head.

This example is labeled as a Kiva Jar as they have been mostly found in kivas. The top is shaped to accept a lid. This kiva jar is considered to be the finest piece in the Mesa Verde collection. The trail guide for the Nordenskiold Ruin No. 16 Trail on Wetherill Mesa says that this jar was found there during the excavations of Jesse Nusbaum in 1928-1929. It has been on display here at the Chapin Mesa Museum since the 1950s.

A miniature of this same jar also seems to appear in the diorama that depicts alcove life after 1200 AD. The dioramas are part of the CCC work of the depression era 1930s. It becomes obvious with experience at Mesa Verde that the dioramas are based on actual locations in the park. The scene that contains the famous pottery example is based on the Spruce Tree House that is right outside the museum.
