corduroy
KOR-duh-roy
In trail-building, logs laid side by side across a boggy path to create a stable surface — a road made of wood over ground that would otherwise swallow you. Walking on corduroy is like walking on piano keys. The logs shift and roll underfoot.
Etymology
English, from the resemblance to corduroy fabric (ridged cloth). The trail-building term dates to colonial American road construction.
