Back to top: Phase 4kAAH within Unit A13
Current version
In the previous AAC strata sequence the construction and use of the pavement were both assigned to phase 2, while in the new AAH sequence they are subdivided into Phase 4jAAH and Phase 4kAAH. In June 2016, C. Chaves Yates revised all strata and phase information to match the updated AAH strata sequence. This page is current as of June 2016.
