Snow presets. packed is the paper's reference snow (E₀ = 140 kPa, ν = 0.2, θc = 2.5 %, θs = 0.75 %, ξ = 10,
ρ = 400 kg/m³). powder is light, soft and compacts readily (it yields in compression before it tears, so a boot
packs a clean print instead of shoving the snow aside; holds a 0.4 m layer elastically). wet is heavy, more ductile and sticky (a larger θs keeps clumps together), with less hardening.
