Expedition 40 answers — 13 November 2026

Slovakia qualifies through the Rusovce aqueduct just outside Bratislava, on the Danube frontier at Gerulata: most of it runs underground, which the prompt explicitly allows, and its tiles still carry the paw prints of a dog that walked across them before firing.

Slovakia lands in the 100 km Farflung band — 2 of this prompt’s 40 accepted answers reach it.

Frequent miss. Morocco is a frequent wrong pin: its khettara channels are centuries old but not Roman, and the prompt asks for Roman work.

Mauritania clears a million square kilometres by around 30,000 — larger than Egypt — so it sits comfortably inside the twenty-nine countries the note counts.

Mauritania lands in the 100 km Farflung band — 1 of this prompt’s 29 accepted answers reach it.

Frequent miss. Greenland is the classic miss: it looks enormous on the map, but it is a territory of Denmark, and the official note rules it out along with Antarctic claims.

Grenada's Carriacou is home to the Shakespeare Mas', a masked whip duel performed when a reciter fumbles a line of Julius Caesar; it is inscribed on UNESCO's Intangible Cultural Heritage list, so the living tradition counts.

Grenada lands in the 100 km Farflung band — 1 of this prompt’s 42 accepted answers reach it.

Frequent miss. Venice, Rio, Trinidad and Cologne are the common picks, and the note is explicit that those famous carnivals sit on national lists only, not on UNESCO's.

Moldova takes its name from the Moldova River, which today runs entirely inside Romania — an indirect link that the note says still counts.

Moldova lands in the 100 km Farflung band — 1 of this prompt’s 24 accepted answers reach it.

Frequent miss. Chad is the usual mistake: the country is named after Lake Chad, not a river, so the wording of the prompt excludes it.

Chile has the monito del monte, a mouse-sized marsupial more closely related to kangaroos than to the opossums around it, and it is native rather than introduced.

Chile lands in the 100 km Farflung band — 3 of this prompt’s 28 accepted answers reach it.

Frequent miss. New Zealand is the common miss: its possums arrived with people, and the note rules them out along with Dominica's opossums.
