3D Permafrost Thaw Cross-Section Simulator

Where the 2D version reads permafrost thaw as a temperature chart, this cross-section renders it as physical ground: a grid of independent soil columns, each thawing downward at its own rate depending on the ice wedge packed beneath it. Once a column's ice wedge fully melts, the surface above it loses support and subsides — the same thermokarst collapse that pockmarks real thaw landscapes — and waterlogged, subsided columns vent rising methane bubbles as their organic matter decomposes anaerobically. Orbit the block to see how uneven the thaw front really is column-to-column, the same unevenness satellite radar surveys use to spot permafrost degradation from orbit before any single borehole trips its alarm.
