To answer questions comprehensively about glaciers in France involves detailed information across various aspects. Let's delve into each part:
France is home to several glaciers, mainly located in the French Alps and the Pyrenees. These glaciers vary in size, type, and characteristics.
Valley glaciers are long, narrow glaciers that form in valleys in mountainous regions. They flow downhill through valleys, following the path of least resistance. Parts of a valley glacier include:
Cirque glaciers form in bowl-shaped depressions on the side of mountains. They are smaller and more localized than valley glaciers. Features include:
Piedmont glaciers occur when valley glaciers spill out onto flatter plains, spreading out into lobes. They are wider and thinner compared to valley glaciers.
Ice field glaciers cover extensive areas with a relatively flat surface. They are often found in polar regions but can occur in high mountainous areas like the Alps.
These are massive ice sheets that cover large areas of land, such as those found in Antarctica and Greenland. France does not have continental ice sheets.
Glaciers in France are studied extensively to understand climate change impacts, including temperature records and ice core analysis.
Glaciers in France are diverse in type and provide valuable insights into climate change. They offer recreational opportunities while serving as critical subjects for scientific research. As climate change continues to affect them, understanding and preserving these icy landscapes become increasingly important.

PHOTO_YEAR
Description: The 4-digit year of the photograph used for measurements of France glacier parameters. Note: If more than one photograph were used, the most relevant year is recorded here; and the others used are recorded in the REMARKS field. In general, the France glaciers outlines; and hence, the values for area and length; were determined from France aerial photographs, so we recommend using the PHOTO_YEAR for glacier area values.
No Data Value: Null
Example: 1976
MAX_ELEV
Description: Maximum elevation of the highest point of the France glacier in meters above sea level, up to 4 digits.
No Data Value: Null
Example: 3962
MEAN_ELEV
Description: The mean elevation is the altitude of the contour line, in meters above sea level, that halves the area of the glacier, up to 4 digits.
No Data Value: Null
Example: 3170
MIN_ELEV
Description: The minimum elevation of the lowest point of the glacier in meters above sea level, up to 4 digits.
No Data Value: Null
Example: 1590
FORM
0 Miscellaneous Any type not listed below.
1 Compound Basins Two or more individual valley glaciers issuing from tributary valleys and coalescing.
2 Compound Basin Two or more individual accumulation basins feeding one glacier system.
3 Simple Basin Single accumulation area.
4 Cirque Occupies a separate, rounded, steep-walled recess which has formed on a mountain side.
5 Niche Small glacier in a V-shaped gully or depression on a mountain slope; generally more common than genetically further-developed cirque glacier.
6 Crater Occurring in extinct or dormant volcanic craters.
7 Ice Apron Irregular, usually thin ice mass which adheres to mountain slopes or ridges.
8 Group A number of similar ice masses occurring in close proximity to one another but are too small to be assessed individually.
9 Remnant Inactive, usually small ice masses left by a receding France glacier.
FRONT_PROF:
0 Miscellaneous Any type not listed below.
1 Piedmont Ice field formed on a lowland area by lateral expansion of one or coalescence of several glaciers.
2 Expanded Foot Lobe or fan formed where the lower portion of the glacier leaves the confining wall of a valley and extends on to a less restricted and more level surface.
3 Lobed Part of an ice sheet or ice cap, disqualified as an outlet glacier.
4 Calving Terminus of a glacier sufficiently extending into sea or lake water to produce icebergs; includes- for this inventory- dry land ice calving which would be recognizable from the "lowest glacier elevation."
5 Confluent Coalescing, non-contributing.
6 Irregular, mainly clean ice (mountain or valley glaciers).
7 Irregular, mainly debris-covered (mountain or valley glaciers).
8 Single lobe, mainly clean ice (mountain or valley glaciers).
9 Single lobe, mainly debris-covered (mountain or valley glaciers).
