About Whistler — Cal-Cheak / Callaghan

Hexagonal columnar basalt in river-valley woodland at the Cheakamus / Callaghan confluence. Exposed faces dry moderately fast — dense columnar basalt is essentially impermeable — but the joints between columns hold water and shaded, moss-covered columns stay slick for days after rain.

Region: Whistler / Cheakamus
Rock type: Basalt
Aspect: east-facing
Altitude: 580m
Exposure: low
Seepage: medium
