Geospatial Summary of Geographical Features on the Juneau Icefield
edit- The areal size of the Juneau Icefield is 1,744 sq mi (4,517 km2)[W 1].
- The largest glacier by area at 874 km2 (337 sq mi) is the Taku Glacier[W 2], while the Meade Glacier is 2nd at 748 km2 (289 sq mi)[W 3].
- There are more than 150 glaciers[W 4] within the boundaries of the Juneau Icefield
- There are more than 240 peaks [W 5] over 2,000 m (6,562 ft) within the general area of the Juneau Icefield, of which only <20 have been climbed.
- Taku Glacier is the longest glacier at 60 km (37 mi) within the Juneau Icefield.
- There are more than 80[W 6] Hydrologic Units within the Juneau Icefield, of which the Field Glacier is the largest Level-10 Basin at 1,062.88 km2 (410 sq mi)[W 7].
- The Taku Glacier is the thickest 4,846 ft (1,477 m) at an elevation of 800 m (2,625 ft) of all measured glaciers in Alaska[JG 1]. The base of the glacier is therefore 677 m (2,221 ft) below sea level.
- The Gilkey Trench(Lower Gilkey Glacier) contains three(3) nunataks which are the largest within the Juneau Icefield at 36.6 km2 (14 sq mi), 38.0 km2 (15 sq mi) and 42.4 km2 (16 sq mi).
- There are four(4) main hydrologic outlets to the Juneau Icefield: Taku River, Berners Bay, Katzehin River and Atlin Lake (to the Yukon River)
- During the time of maximal glaciation(Neoglacial Period) the Gilkey and Field glaciers intersected and possibly formed a tidewater glacier that formed Berners Bay, Juneau, Alaska 58°45′44″N 134°58′47″W / 58.76231°N 134.97981°W
- The Juneau Icefield is Bi-Modal, in that the Neve Area is divided into two(2) nodes (Mount Poletica) and Mount Nesselrode.
Mount Poletica is the North Apex Point . All Hydrologic Basins intersect at the point. 190103030000, 190103030703, 190103010205 and 190701010000
- The Lemon Creek, Ptarmigan, Sloko and Nakima Glaciers are not considered part of the Juneau Icefield because they do not satisfy the Common Source requirement.
Further Investigation
editThere are several areas that indicate that further investigation may reveal more details(however slight) as to the systemic structure of the Juneau Icefield.
- Possible separate glacier near the Field Glacier Neve Zone. Would require ice-penetrating radar (IPR) profiles to determine is a shallow ridge exists and glacial flow analysis by GPS profiling of the area to determine if the flow reflects the hypothetical flow of a separate glacier.
- Vertical face
Definition of Terms/Terminology
editIn this article glaciated/glaciation areas means the glacier area and the adjacent landmass up to the Hydrologic Unit Boundary line, while glacier area refers to the actual area of snow/ice which comprises the glacier.
Glacial Icefield Basics
editThe characteristic definitions of a Glacial Icefield are:
- Extensive area of multiple contiguously interconnected Valley Glaciers having a common source [citation needed]
- Glacier flow is influenced by the underlying topography.
- Geographical area more than 500 km2 (193 sq mi) [citation needed]
- Geographical area less than 50,000 km2 (19,305 sq mi) [citation needed]
- Physically constrained by local/regional topography
- Unlike an Ice-cap, an Icefield lacks a domed form.
Spacial determination of the Icefield Boundary
- Geological/Geographical features(Nunataks) surrounded(completely) by the perennial snow/ice area are considered to be part of the Icefield.
- If a glacier has tributaries that are not connected to the "Common Source", but the main glacier is, the tributaries are still considered part of the Icefield.
Large Icefields in the Western Hemisphere
editNote: No detailed measurements have been found to support many of the reported areal sizes of these Icefields.
Notes
- ^ Common Source Location
- ^ GNIS does not contain an entry for the Stikine Icefield
- ^ The Harding Icefield was split into North and South to adhere to the Common Source rule of icefield definition. The separation line is Bradley Lake59°44′53″N 150°47′36″W / 59.74794°N 150.79333°W to the north, Nuka River59°38′37″N 150°39′49″W / 59.64361°N 150.66372°W traversing Northwest to Southeast to Beauty Bay59°32′11″N 150°38′01″W / 59.53630°N 150.63351°W in the South. This division is identical to why the Taku River divides the Juneau Icefield from the Stikine Icefield.
- ^ The Sargent Icefield was split into North and South to adhere to the Common Source rule of icefield definition. The boundary line is from Kings Bay60°29′00″N 148°38′13″W / 60.48340°N 148.63701°W in the Northwest following the Nellie Juan River60°21′14″N 148°53′15″W / 60.35392°N 148.88749°W in a Southwest direction to Nellie Juan Lake60°13′53″N 149°03′27″W / 60.23146°N 149.05741°W to Day Harbor60°01′27″N 149°06′31″W / 60.02430°N 149.10874°W in the South.
Juneau Icefield Areal Boundaries and Size
editThe Juneau Icefield is reportedly the fifth largest(see table below) Icefield in the Western Hemisphere.
The general geographical boundaries of the Juneau Icefield are defined by the USGS National Hydrography Dataset (NHD) Hydrologic Unit Code. Southeastern Alaska is within the NHD HUC4-1901 region [NM 1]. The Juneau Icefield hydrological area is further defined at the level-8 hydrologic unit code of HUC8-19010301(less the region to the west of the Lynn Canal), HUC8-19010303, HUC8-19010304, HUC8-19070101(Canada) and HUC8-19070303.
The general geographical boundaries of the Juneau Icefield can also be expressed as the area bounded by the Taku River to the South, Lynn Canal to the west, Skagway River on the north. The Stikine Icefield is south of the Juneau Icefield with the Taku River as the North-South delimiter.
The Juneau Icefield area contains over 50(see Juneau Icefield Hydrologic Unit Code Level-8 Summary below) Level-12 Hydrologic Unit Code as determined by the United States Geological Survey{USGS), some of which contain glaciers within their boundaries. Many of those basins are not completely glaciated, but also include the glacial meltwater drainage areas.
The most accurate determination of the area of the Juneau Icefield is completed using the Spacial determination of the Icefield Boundary rules (above).

Juneau Icefield Hydrologic Unit Code Level-12 Apex Points
editA Neve Zone Apex point or ridge is the geographical intersection location of Level-12 Hydrologic Units. The following are the rules for determining Apex locations:
- Multiple(minimum of three) glaciated hydrologic units(Level-12).
- All Hydrologic Units intersection points must be the Neve Zone of the area bounded by the Hydrologic Unit.
The Apex is used in this article to determine if the area satisfies the common source rule as to whether the glacial area is part of the Icefield or is a separate/isolated glacial system.

Landsat Image utilization for Glacier Change
editThe Landsat series of satellites provides a tool for studying Glacier change as a function of time and space. Below are three examples of how Landsat Satellite imagery is utilized to determine the status of a glacier as it pertains to the terminus advancing/retreating. Current Landsat images can be obtained from the USGS LandSatLook website [10]
Example Landsat Image usage in determining glacier terminus migration
edit- Meade Glacier: (N 59 13' 54", W 135 4' 17") [AE 9]
- Mendenhall Glacier: (N 58 25' 58", W 134 32' 43") [AE 10]
- Taku Glacier: (N 58 25' 58", W 134 32' 43") [AE 11]
Methods used by Pelto(2011)
editPelto (2011)[GC 4] demonstrates the use of historical Landsat images(2005) and USGS topographic maps(1948) to show the retreat and Equilibrium Line Altitude of several glaciers on the Juneau Icefield. The following is a summary table of his results and a reverse engineering of his probable methods.

Notes
- ^ The terminus status is as reported by Pelto(2011) based upon his field observations of the terminus area.
- ^ Above Mean Sea Level, feet
- ^ The distance that the terminus has migrated, either advancing or retreating can be calculated using the Haversine formula or by using the built-in capabilities of Acme Mapper.
- ^ Time Delta(2005-1948) is 57 years
- ^ The difference of 600m between from Pelto(2011) may be due to judgement as to terminus position and that the glacier extends around a bend.
- ^ Slight error with the position of the topo map, but otherwise cannot account for the difference.

This article reported 806km2 using the Hydrologic Basin areal size(874.85km2), less the area(69.0km2) which is comprised of the glacial trim area (ie. the area from the glacier's edge to the Hydrologic Basin boundary where the USGS aerial photo shows a non-glaciated area for the area adjacent and below the Hole-In-The-Wall Glacier. Surface area for the Hole-In-The-Wall Glacier was NOT removed).
Equilibrium Line Altitude / Accumulation-Area Ratio
edit- The Equilibrium Line Altitude(ELA) [JG 2] is the altitude separating net gain(accumulation) above this line from net loss(ablation) below this line}}
- The Accumulation-Area Ratio(AAR) [JG 3] is the extent of the upper or accumulation area, above the ELA, divided by the total extent(actual area of the ice surface) of the glacier.
