Feature Numbers

The original excavators of Ashcomb's Quarter (18CV362) assigned numbers to individual features. Excavated contexts belonging to the same depositional basin (e.g. a posthole and postmold) were assigned separate feature numbers such that a postmold was given a feature number and the posthole containing that postmold was given a different feature number. Since DAACS defines features as either excavated contexts that belong to the same depositional basin (e.g. a posthole and postmold or the layers in a single pit) or as single contexts that the excavators recognized as spatially distinct from surrounding contexts, DAACS treated some feature numbers like contexts and combined them into a single feature number. For example, Feature 18 (postmold) and Feature 19 (posthole containing Feature 18) were both assigned to Feature 19, with Feature 18 becoming a context within F19. Feature 66 (postmold) was contained within Feature 37 (posthole) therefore Feature 66 became a context within F37. All Feature Numbers have a F-prefix, which precedes the number (i.e. F01 equals Feature 1).

Feature Groups

Feature groups are sets of features whose spatial arrangements indicate they were part of a single structure (e.g. structural postholes, subfloor pits, and hearth) or landscape element (e.g. postholes that comprise a fenceline). Feature Groups assigned by DAACS have a FG-prefix, which precedes the number (i.e. FG01 equals Feature Group 1).
