Like most things affiliated with the Haines family, the Orestod name is railroad-related. Orestod (pronounced or-eh-stod) is a point on the Union Pacific railroad line (formerly Denver and Rio Grande Western) west of Denver in the Colorado Rockies.
Orestod is the east end of a rail line known as the Dotsero Cutoff, which was built to connect two existing railroad lines. The starting point for this new line was named Dotsero. When it came time to name the opposite end of the line, without much creativity, the point was named Orestod (Dotsero spelled backwards). This part of Colorado is an area frequented by the Haines family on many vacations in the 1970s and 1980s.
