Mutant stones starting on the South Fork of the Snake

Conditions

Mutant stones are firing up on the South Fork, making early morning and late evening prime time. As of August 26, flows were running around 5,950 cfs, solid conditions for working stone patterns near structure and deeper runs. Partly cloudy skies and stable, rising pressure favor a full day on the water.
