- 15. Goats climbing a near vertical brick dam wall to lick the stone for salt and minerals Dams are among the most daunting examples of mankind's engineering savvy, and they're also perhaps the most environmentally impactful, too -- but none of that could keep this brave herd of Ibex goats from scaling the sheer face of the Cingino-dam in Italy. It's a classic illustration of how well this species has adapted to its environment.
