I'm on holidays, but I couldn't resist: I don't get to see these glacial till soils very often. This a roadside cutting at Martyr's Saddle, a moderately adventurous hour or two south of Haast, in south Westland. Always dangerous to classify a drive-by site, but likely a Typic Acidic Brown or Acidic Orthic Brown soil in the New Zealand Soil Classification (although I'm open to the possibility of an undiscovered E horizon pushing it in a Podzol Soils direction). In the World Reference Base I'm leaning towards something like a Brunic, Skeletic Regosol (Arenic or Loamic, Humic or Ochric), over tillic regolith. Seems like protospodic would also be a potential supplementary qualifier given the local climate, but it's disallowed on this RSG at present.Anyway, back to hiking 🥾⛰️ #nzsoils #soilclassification #drivebynerdery
