Well, since you asked about historical information, I'll take a stab at helping you out.
Kahiltna Dome had been known by two other names prior to its current name - Peak Z and Mount Hunter. The name Mount Hunter was inadvertently misapplied to a 14,573-foot peak and the name for that mountain stuck.
Kahiltna Dome was first climbed in 1951 from the Peters Basin by Henry Bradford (Brad) Washburn, Jr., William (Bill) Hackett, Henry Buchtel, and James (Jim) Gale. The account appears on page 217 of the 1952 American Alpine Journal.
