A hybrid Type II-III periglacial lacustrine clay and marl-derived fulgurite from a distribution produced with Type II, other marl-rich (calcareous/carbonate) specimens, Type IV (rock) fulgurites, and abundant Type V (exogenic) spherules; it is also associated directly with vesicular carbon phytofulgurite and glassy, plant fiber-preserving phytofulgurite crusts; Its context at the periphery of a wetland and major creek was predicted. Quaternary geomorphology: end morraine, with loessoid and outwash sediments; Bedrock geology: shale and minor limestone
