In a remote part of Idaho, between the small towns of Pine and Featherville, is a place at the foot of the Trinity Mountains called Paradise. Here there are three same-source formations, or a "Trinity", referred to as Landa, Bridge, and Paradise. We currently collect Trinity exclusively at the Landa source. The other two sources remain undeveloped. The Sawtooth and Boise National Forests border all three sources. These forests contain some of the finest unspoiled wilderness in the United States.

Paradise sits atop the Idaho Batholith, the geological name for an enormous underground granite formation estimated to be more than 20 miles deep. The batholith covers more than 26,000 square miles, making it one of the largest in the world. The Trinity source flows to the surface of the earth through crystal-lined granite faults by means of geothermal pressure, and reaches the surface at 138°F.

The power and heat of the 2.2-mile-deep Trinity source bring the water to the surface as a natural rock spring without any boreholes, pumps, or other man-made extraction devices. This natural system contributes to the source's purity and infuses Trinity with natural minerals.

The Idaho Batholith is a huge mass of granite. At 26,000 square miles, it is larger than the state of New Hampshire.
