Description:

Abstract:

This dataset presents a delineation of the maximum extent of fluvial occupation detectable from vegetation patterns at Exit and Paradise Creeks in Kenai Fjords National Park, Alaska for 1950 conditions. This comprehensive 1950 surface includes the active braid plain, taken as the suite of wetted channels and largely unvegetated intervening bars (Curran and McTeague, 2011), the inactive braid plain, considered here as vegetated formerly occupied channels and bars still accessible by braiding without substantial bank erosion, and surfaces occupied by former glacier drainage but potentially no longer accessible by braiding. For simplicity, this surface also includes isolated non-fluvial features such as bedrock or moraines stranded within the fluvial features.Limited photo resolution and lack of elevation data precluded differentiating the active and inactive surfaces.

Purpose:

This dataset supports a study of the fluvial and glacial development of the area immediately downstream of Exit Glacier on Alaska's Kenai Peninsula. Exit Glacier and the associated Exit Creek are within Kenai Fjords National Park, and their changes over time are of interest to park visitors and managers.

Source_Contribution:

This 1950 USGS aerial photo georeferenced by National Park Service provided the earliest high resolution image of the study area and was used for interpretation of 1950 fluvial and glacial conditions.

Process_Step:

Process_Description:

Using the oldest high-resolution aerial photography available, a 1950 series used by the USGS for developing topographic maps, and patterns of preferential vegetation growth along channel margins that preserve evidence of channel form on a multi-decadal scale, we mapped the envelope of channels, bare areas, and vegetated areas showing channel patterns at a scale of 1:2000. For simplicity, this surface also includes isolated non-fluvial features such as bedrock or moraines stranded within the fluvial features. Fluvial evidence from areas associated with breaches in the prominent moraines dated in the 1800s other than the 2012 location of Exit Creek were excluded. Features were delineated as polygons.
