The science

A source with a planetary record.

01

Mars-like rocks

Del Puerto Canyon exposes ancient ultramafic rock formations studied as analogs for the mineral environments of Mars.

02

Alkaline mineral water

As water moves through this geology, it gathers a naturally alkaline profile and a distinctive mineral composition.

03

Same chemistry

The mineral signatures that make this landscape scientifically relevant also shape the water emerging at Adobe Springs.

04

Why it matters

Knowing the source means understanding the water: its geology, its mineral record, and the land that protects it.

Blank et al., Planetary and Space Science, 2009.

The source

Adobe Springs, Del Puerto Canyon.

At the eastern edge of California’s Coast Ranges, Adobe Springs rises from a protected 217-acre source in Del Puerto Canyon.

The canyon’s rare geology gives the water its mineral character. Its stewardship keeps that record intact, from rock to spring to bottle.
