Deepest SLF stationsWSL Institute for Snow and Avalanche Research SLF
HS in the SLF API schema is “height of snowpack, total thickness of snowpack, instantaneous, cm”. HN_1D is “height of new snow during the last 24 hours, cm”. Both are printed in those units. A distance to a guide city is great-circle kilometres between the station coordinate and the guide-city coordinate, shown only when it is 25 km or less. It is not the resort’s own snow report.

These seven stations are a fixed list, not a ranking of every American ski resort. SNWD is snow depth and WTEQ is snow water equivalent, in the units the NRCS service returned (inches). The date is the latest daily value in the ten-day window that was not empty.

How to read this
The Swiss table is a ranking of snow depth at SLF IMIS stations on the measure date in the file. Most of those stations sit high, often above the tree line, because that is where the avalanche-warning network measures. A large number there is not the depth at a village, and a small number is not a statement that a ski area is closed.
Early in the season the deepest figure can be a few tens of centimetres. The page prints that figure rather than a typical-winter expectation. Zero is a real reading and is counted in the station total; the table shows the deepest 25 so the top of the list is visible.
New snow is the 24-hour HN_1D value on the same row, in centimetres. A dash means the file had no HN_1D for that station.
This is not an avalanche bulletin. SLF publishes that separately. This page does not say whether a slope is stable.

Quick answers
- Where is the snow deepest in the SLF file?
- 18 cm at Gandegg (2710 m) on 2026-11-03. The table lists the next stations in the same file.
- Is this the ski resort’s snow report?
- No. These are SLF measuring stations. A guide city is mentioned only when its coordinate is within 25 km of the station, and that distance is calculated from the two coordinates.
- What unit is the snow depth in?
- Centimetres. The SLF API describes HS as the height of the snowpack in cm, and HN_1D as new snow over the last 24 hours in cm.
- Why are so many stations near zero?
- Because the file includes them. On this read 259 of 262 stations have a snow depth above 0 cm. The measure date is the date SLF wrote on the row, which may be the previous calendar day.
- Does a snow depth say the backcountry is safe?
- No. Snow depth is a thickness. Avalanche danger is a different SLF product and is not copied onto this page.
- What about the U.S. numbers?
- They are USDA NRCS SNOTEL daily values for seven named stations, in inches, and only when that service answered. They are not mixed into the Swiss ranking because the unit and the network are different.
