Escalante was initially used for beta-testing, before the park was opened to guests. It is located in the Unclaimed Territories. There is a remote diagnostic facility below Escalante.
Escalante was covered in sand by the time that William took his first visit to Westworld. Ford had the town excavated and the buildings rebuilt and restored some time before the events of the final episode of season one. The gala for the premiere of his Journey Into Night narrative takes place in Escalante.
