Histogram showing weight distribution of pumice clasts. State of Florida Investigations Pumice artifacts were recovered from 19 proveniences associated with the State of Florida investigation of the Miami Circle at Brickell Point site (83DA12). Thirty-seven pieces representing 27 clasts were found. Proveniences include excavations around a septic tank, located 17 m west of the Miami Circle feature, and features in the N34 or “Valley of the Holes” area. The presence of pumice artifacts in these areas helps confirm that this material is distributed across the property. Vertical distribution is similar to that noted for the Miami Circle excavation units. One meter square units excavated adjacent to a septic tank produced 9 pumice clasts from multiple levels. Within the N34 or “Valley of the Holes” area 18 pumice clasts were recovered from midden deposits within 10 of the holes or basins carved into the limestone bedrock Other Site Areas Three clasts of pumice were recovered from the University of Houston fieldschool in 2000, located between the Miami Circle feature and the N34 or “Valley of the Holes” area. Other proveniences across the site include Trench 1, one of the demolition trenches dug to remove the footings of the buildings comprising the Brickell Point Apartments. SDA9S Salvage excavations on the Sheraton Hotel property (referred to here as 8DA98), directly to the south of the lot where the Miami Circle was found, also produced pumice artifacts. Both lots are components of the larger Brickell Point site, which extended west and south of the point where the Miami River meets Biscayne Bay. Bob Carr directed work at the Sheraton component in 1980-1981 prior to the construction of the hotel (initially a Holiday Inn) (Carr and Ricisak 2000:266-267). Excavations included a north-south trench and other tests, which uncovered holes cut into the limestone, similar to those that make up the Miami Circle feature. Six pumice artifacts recovered during the excavations are curated at the Historical Museum of Southern Florida. These artifacts help confirm that the deposits at the Sheraton component are likely of similar age and nature as those encountered at the Miami Circle component. Discussion Technological Place of Pumice Artifacts John Goggin (n.d.:615-616) suggests that the flat surfaces and facets observed on some pumice artifacts are produced by grinding and smoothing tasks related to woodworking. Some of the additional modified pumice artifacts, like those with cup- shaped surfaces, also were likely used in polishing wood. A role in woodworking makes sense, since many of the shell artifact forms and some of the bone artifact types identified from the Miami Circle site are best described as woodworking tools (Wheeler 2004a, 2004b). Direct evidence of a sophisti- cated tradition of woodworking is found at the Key Marco site,
