Indigenous people of the Cook Inlet travelled and lived in the area.

Jack Easterday was the original homesteader for this primary 480 acre parcel who built the A-frame in the 1960’s to prove out his homestead.

The 1990’s ushered in a Spruce Bark Beetle invasion of the forests of the Kenai Peninsula, which peaked around 1996 and killed 80%-90% of the mature spruce trees.

Around 1995, with most of the mature spruce trees dying, Jack sold his homestead to Buffalo Timber Co. who logged the standing yet dying spruce for lumber.

Once the logging operation on the upper non-sloping reaches was complete, Buffalo Timber put the logged property up for sale and Cliff Gill purchased it as it was large enough to accommodate an airstrip.

Twin Rivers Wilderness grew out of the evolution of the forest and land. As the spruce regrew and new meadows and alder thickets established themselves where once just stumps remained, Twin Rivers was reborn.
