In 2009 Curl spent time in Transnistria, officially the Pridnestrovian Moldovan Republic, a Leninist post-Soviet frozen conflict zone between the Ukraine and Moldova. A socialist state that borrows from the Soviet model, Transnistria is a police state of 400,000 inhabitants. Although unrecognised as a sovereign nation by any UN country, Transnistria produces its own passports, currency and stamps and runs its own police force and army. Curl returned having photographed scenes previously unseen outside the republic.
In 2010 Curl crossed the western side of the Omo River Valley in southwest Ethiopia from Dima across tribal lands southwards towards Kenya. He passed through the western Surma tribal lands, through the lands of the Bench, Dizi and Nyangatom tribes finishing on the eastern side of the Omo in the lands of the Hamer. Curl travelled with tribal escorts and scouts, changing companions from tribe to tribe, most of whom are cut off from outside influence and still continue a very traditional way of life. Curl encountered people who had never seen white men and is one of a handful of Westerners to travel across this land on foot where tribal conflict is frequent.

2010 saw Curl travel with the Rendille tribe in northern Kenya, using camels to cross the Kaisut Plain, the Ndoto Mountains and the Karoli desert. There he encountered the people of the Pokot, Samburu, Gabra and Turkana tribes. Later in the year, Curl with anthropologist Luke Glowacki from Harvard University carried out an expedition across the Danakil Depression, a volcanic desert in Ethiopia often called 'the cruellest place on Earth' and home to the Afar people. It is the hottest place on Earth, with temperatures in the Danakil have been known to pass 60 degrees Celsius. Curl and Glowacki walked the ridge of volcanoes southwards, using camels to transport their water and provisions.
