Just right of the big 5.4 off-width fissure, carefully climb the groove. To climb the right crack, go straight up as the groove turns into an obvious crack above to the top. To climb the left crack, angle left about 25 feet up following the slanting layback crack-flake.
This enjoyable route is long by Carderock standards, and along with its left variation and the two adjoining more difficult routes makes a good option when the rest of the crag is occupied.
Sterling's Double Cracks can be accessed from below at low water via a ca. 5.6-5.7 traverse downstream just above the water for about 30 feet starting at Trudi's Terror. Or one can set the top rope - on the pointed and tallest crag about 30-40 feet downstream from Trudi's Terror - and rappel down to a stance (near an obvious off width fissure) which is dry even at regular water height.
