Why does some muddy ground on paths never seem to dry out even when it hasn't rained in weeks?

It's usually groundwater seepage or springs. Water percolating through soil and rock emerges at the surface where geology shifts, creating persistent wet patches that stay damp regardless of recent rainfall.

Why do paths get wider and muddier over time?

When puddles form, walkers step around them to avoid getting wet. This tramples vegetation on either side, creating new muddy tracks, and the cycle repeats until you end up with a wide braided network of parallel wet paths instead of one narrow route.

Does walking on paths actually make them more waterlogged?

Yes. Repeated footfall compacts the soil, squeezing out air pockets and reducing how well water can drain through. What once drained adequately becomes increasingly waterproof and prone to puddling, especially on popular routes.

Why Some Paths Stay Dry While Others Turn Into Swamps

Bedrock, soil, slope and drainage determine whether rain soaks away or remains near the surface. Add peat, heavy footfall and poor drainage, and one path stays firm while another becomes boggy.
