polish geological maps of holocene surfaces dont show ash deposits. maybe polish geologists just suck but having an ash bed of an exactly known age is valuable data for any geomorphological analysis. ive looked for a polish map which shows any mention of what would be an excellent marker bed for tracking stream or river meanders, landslide dating, i mean, theres lot you can do with a widespread ash layer. i worked in a project that tracked holocene lahars on a volcano and a single bed that could definitely be known as a 1943 bed would be fuckin great. so either geologic maps in poland dont show ash deposits because they arent there or polish geologists are absolute dogshit at their jobs.
