This web site was created to function as a repository for information and photographs generated during research and survey projects performed by Glendale Community College, Scottsdale Community College and Paradise Valley Community College from 1988-2004. Subsequent research conducted by members of various Chapters of the Colorado Archaeological Society will also be posted here. Many of these members have decades of experience in the field and laboratory. Over the last 23 years, we have conducted private property survey's of the Mitchell Springs and Champagne Spring community's. As time permits, earlier publications and reports will be linked for easy access. Current research involves test excavations at the Mitchell Springs Ruin Group and Champagne Spring Ruins. We are also working on a project that explores the chemical composition and trade patterns of San Juan redware in the Mesa Verde region and SE Utah.

Many thanks to the Verde Valley Archaeological Center and the Arizona Archaeological Society for all of the help.

Items above are from the Mitchell Springs - Sector 11 Great Kiva floor. Shown here are non-local spondylus beads and a complete jet ring. This and 3 partial jets rings were found on one of the many floor surfaces. Approximately 50 turquoise beads measuring 3.5 mm with 2 mm inlaid jet beads were also found on the floor with a broken Chaco B/W Cylinder mug.
What a crew! I am always amazed at the level of interest and the conscientious way in which our participants perform. All but 2 of the 28 participants had previous excavation experience under the tutelage of some excellent archaeologists and boy are they good!. The third 2014 Field School at Mitchell Springs Ruin Group concluded yesterday and many fascinating discoveries were made while new mysteries came to light and others were solved.
Work continued on a Basketmaker III pitroom (photo left) which contained an interesting mix of tools that were left behind on the structure floor. A slab metate was laying face down on the floor near a bell shaped pit that was apparently used for food storage. Its roof was of pole and brush style and was partially covered with thin sand-
stone slabs. Entry was made through the southern wall and at least one large sandstone step was found to the south side of the structure (photo above right) where it was installed to reach the prehistoric ground level. Water would have been diverted from the entry to prevent the flooding of the pitroom. It appears there was no one living nearby for at least the next 10 years as no post occupational trash was found in the structure.
Our excellent crew leaders and seasoned veterans continued to demonstrate their ability to do exemplary work. Two crews worked on the partial excavation of Structure 25 (photo below) which is a deep pitstructure that was abandoned around A.D. 840 or 850. It was thoroughly burned and more than 100 tree-ring samples have already been collected. This building contains over 30 square meters of floor space and probably served as a meeting place for large groups of people. After a decade of sprinkler irrigation on my yard, a depression developed and our subsequent test of it revealed this structure. The floor is around 3 meters below today's ground surface and contains a slumping bench on the south end of the building. We've been working in this deep pitstructure and this week we reached the top of the wingwall (photo at

right). The structure fill contained several broken metates, broken cooking and serving vessels and pockets of burned brush. During our last session, we will reach the floor of Structure 25.
A few meters to the west, nearby Pueblo A is a multi story greathouse with an appended Tri Wall structure on its west side. This structure is different than previously examined Tri Walls in that the center chamber is a platform that was probably used for making smoke signals or for large cooking events. Only about a dozen of these buildings are known to exist and little is known about their intended function.
Pueblo A contains at least 21 ground floor rooms including a central kiva. Tests in this kiva (Kiva A photo to the left) have revealed a Chaco style kiva with patches of fine tabular masonry. It was built into the center of the pueblo and was at least 2 stories tall. An interesting ventilator feature was built into the south end so as to avoid the problem of providing airflow when second story walls interfere with the shaft.
On the east side of Kiva A lies Room 18 (photo to right). It was thought that this room would have served as storage but our tests suggest it probably served a function related to the central kiva. A doorway through the west wall of Room 18 indicates there is another room built into the interstitial space between the kiva and the kiva enclosing wall. An ancillary single stone width wall was appended to the south wall.
A portion of the second story floor/first story roof collapsed into the room and the 'finish' of the second story floor was visible in the casting. Plaster was spread over the top of the 1st floor roof leaving reed and small stick impressions. Many of the roof casts found inside the room contained corn impressions ....some of which appear to be quite large compared to most of the burned cobs recovered in the room.
On the last day, a complete McElmo Black-on-white bowl (see right) that had dropped from the 2nd story floor was found in the northwest corner of the room.
Until next time...
