The data files LITHICS.TXT and LITHICS.XLS contain data on the quantities and types of lithics recovered from the 553 collection lots in the Machalilla National Park survey. LITHICS.TXT is an ASCII text file; LITHICS.XLS contains the same data in the form of an Excel spreadsheet. Each line represents one collection lot. There are 553 lines in the text file, each with 30 variables separated by commas. The variables are, in the following order:
| Lot Number | |
| Total number of flaked and ground stone artifacts |
Flaked Stone Artifacts
| Preform | |
| Flake knife (no obsidian flake knifes recovered) | |
| Blade knife (all materials except obsidian) | |
| Blade knife (obsidian) | |
| Side scraper | |
| End scraper | |
| Puncturing tool | |
| Drill | |
| Rimmer | |
| Burin | |
| Burin spall | |
| Projectile point (small, arrow?) | |
| Projectile point (large, lance?) | |
| Projectile point (undefined) | |
| Core | |
| Axe | |
| Micro flake (debitage from knife tools or projectile points?) | |
| Debitage | |
| Undefined flaked stone artifact (most likely debitage) | |
| Total flaked stone artifacts |
Ground Stone Artifacts
| Mano | |
| Metate | |
| Undefined mano or metate | |
| River stones, small (polishing pebble?) | |
| River stone, large | |
| Large worked stone (chair, column, or sculpture fragment) | |
| Other ground stone | |
| Total ground stone artifacts |
The first line of the ASCII text file, for example, looks like this:
1,2,,,,,,,,,,,,,,,,,1,,1,2,,,,,,,,0
This indicates that the data pertains to collection lot 1, which contained a total of 2 flaked and ground stone artifacts. Amongst them, there were 0 preforms, 0 flake knifes, 0 blade knifes of materials other than obsidian, 0 blade knifes made of obsidian, 0 side scrapers, 0 end scrapers, 0 puncturing tools, 0 drills, 0 rimmers, 0 burins, 0 burin spalls, 0 small projectile points, 0 large projectile points, 0 undefined projectile points, 0 cores, 0 axes, 1 micro flake, 0 debitage, 1 undefined flaked stone artifact, and so a total of 2 flaked stone artifacts. There were also 0 manos, 0 metates, 0 undefined mano or metates, 0 small river stones, 0 large river stones, 0 large worked stones, 0 other ground stone, and so 0 total ground stone artifacts.
The last, or 553rd, line of the ASCII text file is:
553,1,,,,,,,,,,,,,,,,,,,1,1,,,,,,,,0
This indicates that the data pertains to collection lot 553, which contained a total of 1 flaked and ground stone artifacts. Amongst them, there were 0 preforms, 0 flake knifes, 0 blade knifes of materials other than obsidian, 0 blade knifes made of obsidian, 0 side scrapers, 0 end scrapers, 0 puncturing tools, 0 drills, 0 rimmers, 0 burins, 0 burin spalls, 0 small projectile points, 0 large projectile points, 0 undefined projectile points, 0 cores, 0 axes, 0 micro flake, 0 debitage, 1 undefined flaked stone artifact, and so a total of 1 flaked stone artifacts. There were also 0 manos, 0 metates, 0 undefined mano or metates, 0 small river stones, 0 large river stones, 0 large worked stones, 0 other ground stone, and so 0 total ground stone artifacts.
