This is a view of the two excavation areas, separated by the back hoe trench.
The upper area was gridded off as a 5m by 5m big block. Vice Chair Cathy McCool and member Joe Beavin are standing in the middle of the upper area.
The lower area in the foreground has had the upper 70cms mechanically removed with the back hoe.larger photo

While most people associate professional archaeology with trowels and whisk brooms, there are times when shovels and back hoes are also important tools! The use of the back hoe at the Chandler Site allowed us to determine site stratigraphy in a matter of hours, rather than weeks, and it also allowed us to remove the distrubed overburden (distrubed by numerous collectors pits and backdirt) over the intact Early Archaic and Paleoindian deposits in the lower unit area. Without the back hoe we could never have finished our excavations in the lower area nor had a handle on the stratigraphy. larger photo

Member Joe Beavin assists Bruce Moses in gridding the site using a Total Data Station. Precise measurements are yet another important tool in determining locations and relationships of cultural materials as they are excavated from a site.larger photo

This current picture shows the back hoe trench that separates the upper and lower areas of the site. The trench allowed us to see the site stratigraphy and plan our excavations accordingly.
There were two main excavation areas, separated by a 5m (long) by 1m (wide) by 3m (deep) back hoe trench.
In the upper area a 5m by 5m grid was laid out - consisting of units 5 through 29). The upper excavation area was focused on exposing the Late Prehistoric and Archaic components. This area was chosen because it had little disturbance from collecting.
The lower area was where a great deal of disturbance from collecting had taken place. It was decided to remove a 3.5m by 3.5m by 70cm deep section. Removing this section created the opportunity to start excavations at the interface between the bottom of the Archaic Midden components and other more discrete Early Archaic and Late Paleoindian deposits below that level.larger photo

The Field Office - a series of tables were set up on the north end of the site to process all outgoing and incoming field sacks and unique items recovered during the excavations. Maintaining proper control of cultural materials is vitally important to properly documenting and subesquently writing up the report on a site. larger photo

Field Office
This is the office area at the site. It is vitally important that all materials collected are properly logged and controlled. Cathy McCool (foreground) checks level notes and prepares to create a new field sack.larger photo

Excavation in the upper 5m by 5m area begins! Note the concentration of burned rock. This is the top of the compressed Archaic Midden. The upper 10cm - 15cm contained numerous Late Prehistoric arrow points along with Bison Bone.larger photo

The place where rabdotus go to die. This is a typical field sack of material recovered in the upper midden area. Flake and snail counts were astronomical in the upper 40cms of the midden deposits. These deposits also included small amounts of bone and mussell shell. larger photo

Screening Party!
Once soil has been excavated from its unit is is then placed in a bucket and taken to the screens. The soil is then processed through the screen and any cultural materials removed and bagged. Cultural materials include, flakes, bone, mussel shell, snail shells, stone tools, ground stone, and any other object used by or modified by man.

Typological Case of materials recovered from the Chandler Site.
Across the top row are a variety of Late Prehistoric arrow points, including Scallorn, Edwards, Cuney, and Perdiz.
The second row consists of Transitional Archaic dart points such as Ensor, Ensor-like, and Fairland. Also in this same row are a reworked Cornertang Knife, a beveled knife, and an archaic drill.
The third row consists of Late Archaic dart points such as Frio and Marcos.
The lower left corner exhibits Middle Archaic fomrs such as Pedernales and Bulverde.
Also shown in this image is a single sherd of Leon Plain ceramic that was recovered in the upper 5cms of the upper units. (shown in the bag with a UI - unique item - identificaiton tag.)
The lower row, middle, shows a variety of the Late Paleoindian lanceolate form recovered and includes Scotsbluff, Angostura, Golondrina, and St. Mary's Hall types.larger photo

This image shows the other half of the typological collections recovered from the Chandler Site.
The upper row shows a variety of Early Archais stemmed projectiles, including Martindale, Travis, and Nolan points. Immediately below these projectiles are two Early Triangulars and a unifacial Clear Fork tool.
The lower row is a continuation of the Late Paleoindian materials and includes possible First View and Plainview types as well as Golondrina, Barber and Wilson points.
The materials in the upper right are examples of mussell shell, Bison Teeth and deer bone and also include representative lithic materials recovered from the site including Edwards chert biface fragments, possible heat treated chert biface fragments, chalcedont, and a lump of clear quartz crystal - most likely from the Llano Uplift area.larger photo

CO PI's, Bruce Moses and Clint McKenzie, along with member Joe Beavin, continue to bring down the untis in the lower excavation area. Note that all of the large rocks are being left in place as they excavate around them. By leaving the rocks in place an excavator can soon determine if they have a random assortment of rocks or part of a man made feature such as hearth or storage pit. Only once the rocks have been documented and mapped are they removed. If a feature is discovered it is thoroughly documented by drawings and photography and all artifacts associated with feature carefully collected and observed.larger photo

As excavations in the lower area commenced a number of Early Archaic features were exposed. In this image, the excavation area has been cleaned and dressed in preparation for photography and a north arrow and scale are being placed on the floor of the unit.larger photo

Once level 19 was reached in the lower area the flake counts dropped significantly and it was decided to remove the gravel deposits by shovel rather than with a trowel. We are now approxiamtely 2m below the surface.
