Unformatted text preview: Horizontal dimensions Grid coordinate system Establish a site datum Vertical dimensions Excavate in levels 1. stratigraphic (natural) levels 2. arbitrary levels (done in 10 cm levels) =================================================== NEW WORD In situ = means am artifact in original position =================================================== Munsel color book – used to record the color of the dirt-never did just to dig. You need a purpose a question (a possession)-wash and catalogue all artifacts-Radiation offset- way of mapping out entire site two means by which we do surface collection -arch site less then 100meter diameter we use radiation offset-arch site larger than 100meter diameter we use grid system asimuth- degrees distance- distance from center elevation- elevation above datum UTM aims a center of site HOWEVER if site is larger then 50metrs then take three UTM points and triangulate center...
