This forest remnant south of Geikie Inlet has been cleanly sheared off below 1600 feet, giving a precise elevation for the height of ice when Little Ice Age glaciation had reached its maximum extent in Glacier Bay about 250 years ago. Ice removed all life from surfaces below this elevation; when this photo was taken in the 1960’s, plant succession had proceeded only to the alder stage, and conifers had yet to reassert dominance.
