Agenda

Project Location Overview Contract Line Items (CLINs) Construction Challenges - Summarized Site Walkthrough

Project Location Overview

Historical cornucopia: 1150 CE – 1550 CE

Ancestral lands for at least 23 tribal nations

Rich in archaeological artifacts:

− Cavates − Pottery shards − Tools − Paleoindian points − Burial grounds

Where are we?

Cochiti Pueblo guided Adolf Bandelier to the cliffs in 1880.

Established as monument in 1916 by Woodrow Wilson

Civil Conservation Corp (CCC) – constructed infrastructure (1930s)

Historic Mission 66 Corridor

NPS starting counting visitors in 1932 with 4,200. Peaked in 1994 with 430,000 visitors with a current steady annual visitation of 200,000 – 250,000.

Projected to have 18 Million visitors in 100 years.

Why Bandelier?
