Australia's highest mountain is Big Ben on Heard Island, an active volcano far south in the Indian Ocean. The mainland's tallest peak is not volcanic, but territories count, so Big Ben carries Australia.

Australia lands in the 100 km Farflung band — 3 of this prompt’s 46 accepted answers reach it.

Frequent miss. Indonesia is the usual miss: Puncak Jaya is the country's highest point, but it is limestone, not a volcano, and the note singles that out.

Myanmar was held as a province of Kublai Khan's Yuan dynasty for 18 years, and Korea's Goryeo kingdom became a Mongol vassal — vassal states count, so both countries qualify.

Myanmar and South Korea both land in the 100 km Farflung band — 2 of this prompt’s 31 accepted answers reach it.

Frequent miss. Japan and Vietnam are the frequent wrong pins: both were invaded and both drove the Mongols out, which the note explicitly excludes.

Czechia's ruined castle tower near Mladá Boleslav was surveyed in 2026 at 7.3 degrees, nearly twice Pisa's 3.97, and the prompt accepts ruins as well as standing towers.

Czechia lands in the 100 km Farflung band — 1 of this prompt’s 28 accepted answers reach it.

Frequent miss. The usual error is naming a famous leaning tower without checking the angle: anything under 3.97 degrees fails, however well known it is.

Saint Kitts and Nevis is a constitutional federation of two islands, the smallest federation in the world; in 1998 Nevis voted 62% to secede, short of the two thirds it needed.

Saint Kitts and Nevis lands in the 100 km Farflung band — 1 of this prompt’s 27 accepted answers reach it.

Frequent miss. Spain and South Africa are the common traps: both are often described as federations in practice, but they are unitary states under the note's test.

Croatia's Stari Grad Plain on Hvar is a UNESCO World Heritage cultural landscape where Greek settlers laid out field divisions 2,400 years ago, and vines still grow inside them.

Croatia lands in the 100 km Farflung band — 1 of this prompt’s 10 accepted answers reach it.

Frequent miss. Georgia is the frequent miss: its wine-making tradition sits on UNESCO's intangible heritage list, not the World Heritage list this prompt asks for.
