View south from the air of the Tok Cutoff Highway offset by the Denali fault. The right-lateral offset is 6.9 +/- 1.0m. This measurement is the addition of 5.0m of right-lateral slip measured across the brittle fault zone and 1.9m of fault-drag related right-lateral slip. The vertical offset is <1m.

View north of the Tok Cutoff Highway offset by the Denali fault. Note the right-lateral drag of road into the fault zone. The right-lateral offset is 6.9 +/- 1.0m. This measurement is the addition of 5.0m of right-lateral slip measured across the brittle fault zone and 1.9m of fault-drag related right-lateral slip. The vertical offset is <1m.

Southward looking aerial view of the Tok cutoff Highway offset by the Denali fault. Fractures perpendicular to the road are present near the rupture and accommodated bending. 5.0m of right-lateral offset occurred across the main two fault traces and 6.9m of right-lateral offset occurred across the entire rupture zone.
