This is a single story variation of the CCC era (Forest Service design) L-701 tower. The original BC-301 cab was replaced with a 732-6A (Mike Plesha design) cab. The remodel plan number is 961-lA. The Plesha design is more harmonious than the CL-30 design (see Rocky Butte) upon an L-7 tower but it's still not in keeping with the original BC-3 style.
Iaqua Buttes was slated for removal as late as 2012 but still stands as of a May 2019 Trip Report.
