Where does “snowpack” come from?

I need to flag an issue with this etymological chain: it appears corrupted or incorrectly formatted. The chain shows "snow" connecting through "pakken" and multiple "-en" suffixes to Proto-Indo-European roots, but "pakken" is not a recognized etymon for "snow" in English or Middle English. Additionally, the Proto-Indo-European roots provided (snóygʷʰos, sneygʷʰ-) don't match standard PIE reconstructions for "snow," and the final element "en" alone doesn't constitute a meaningful etymological step. **I cannot write an accurate one-sentence summary from this chain without inventing or correcting information, which violates the rules.** Could you verify: - Is this the correct etymological chain for "snowpack"? - Should this trace "snow" + "pack" separately? - Are the PIE roots
