Lake Louise + Moraine Lake glacial-blue is the recognized 'August glacial-blue water reads sapphire' — the heritage Wenkchemna Range glacial-fed lakes peak August. The recognized scientific explanation: the heritage Bow Glacier + the heritage Wenkchemna Range glaciers grind glacial-rock-flour (the heritage 'rock flour' — micrometer-scale rock-particle suspension) into the meltwater that feeds Lake Louise + Moraine Lake. The rock-flour suspends in the lake-water and reflects the heritage 'wavelength-of-blue-light' (the recognized 'short-wavelength-blue' light-scattering register), producing the heritage 'glacier-blue' or 'glacier-turquoise' color. August is the recognized peak-color window because: (1) glacier melt-rate peaks late summer; (2) the heritage Lake Louise + Moraine Lake water-temperature peaks the heritage 5°C / 41°F maximum (still glacier-cold but at recognized peak-clarity); (3) the heritage Wenkchemna Range snowmelt-rate peaks the recognized August window. Pack: Hoka Speedgoat 5 + Arc'teryx Atom LT + Patagonia R1 + Patagonia Houdini packable shell + 3L hydration + bear spray + bear-bell + Pajar shearling trapper hat + lightweight wool gloves + mineral SPF 50 + Lack of Color wide-brim hat.
