Parameters used to estimate Holocene RSL change at Icy Point Parameters used to estimate Holocene RSL change at Icy Point Parameters used to estimate Holocene RSL change at Icy Point Parameters used to estimate Holocene RSL change at Icy Point
(A) Terrace B inner edge* 47.3 ±1.7 Determined from 25 lidar profiles; error is two standard deviations to the mean
(B) Terrace B sediment thickness 3 ±1 Estimated from outcrops and pits; error spans the range of observations
(C) Terrace B shoreline angle§ 44.3 ±2.0 C = A – B; error is the square-root of the sum of squared errors
(D) Modern shoreline angle 2.0 ±0.8 Determined from 50 lidar profiles; error is two standard deviations to the mean
(E) RSL change at Icy Point# -42.3 ±2.1 RSL change at Icy Point, west of the Fairweather fault ,since 5.5–9.4 ka
