To collect pieces of this rare rock, a flight must be chartered from the city of Yellowknife to a small outcrop approximately 300km north of the city. Flights leading to the small, remote island can be complicated by extreme weather conditions such as choppy waters, severe wind, blizzards, and low visibility and chartered flights are not always able to land. Once arriving at the site, one will first notice a metal silo and once on shore, a closer inspection reveals the title Acasta City Hall, established 4.03 Ga (billion years ago), which is a building used for research expeditions and student field trips. From this site, Rock of Ages’s owner Mark Brown and others are able to collect less than 800 pounds of rock each trip from the Rock of Ages claim. Due to expensive nature of collecting, chartered flights to the Rock of Ages occur every other year or sometimes less.
