ANTH 102 LAB 5 Activity 4: Using Dendrochronology in the American Southwest Task Our team is working in the American Southwest, at the Pueblo site of Snake-in-my-boot Ranch. The site consists of eight rooms that were built sometime between 1250 CE, when the site was first established, and 1300 CE, when the site was depopulated. Due to the arid climate and good state of preservation, we have recovered a number of wooden roof beams from five of the rooms. These have been analyzed at the Tree Ring Lab in Tucson, which provided cutting dates for each of the beams. The dates from the tree ring samples have been listed below for each room. Based on the tree-ring data, we can estimate the construction date of the rooms. Use this information to answer questions 32 39. Room 1 (7 beams) Room 5 (12 beams) Beams (x6) - 1250 CE Beam (x1) - 1255 CE Beam (x 1) - 1265 CE Beam (x 1) - 1275 CE Beams (x 10) - 1286 CE Room 2 (0 beams) Room 3 (10 beams) Room 6 (12 beams) Beams (x 10) - 1286 CE Beams (x 2) - 1290 CE Beams (x3) - 1257 CE Beams (x7) - 1260 CE Room 7 (O beams) Room 4 (0 beams) Room 8 (10 beams) Beams (x2) - 1295 CE Beams (x8) - 1300 CE Questions (Refer back to pages 5-7 of the digital lab packet for more help with this activity.) 38. If Room 6 was built in 1286, what processes might account for the two later beams?
