A climbing site on Risa whose rock face alters its pitch as climbers ascend, where Travis Mayweather was injured during shore leave in 2152.
Galartha is a climbing spot on Risa, mentioned in the Enterprise episode Two Days and Two Nights.
When part of the crew are granted shore leave, the helmsman Travis Mayweather chooses to go rock climbing at Galartha, a cliff said to change its angle while a climber is on it. He falls and hurts his leg.
Treated at a Risan hospital, he has an allergic reaction to the painkiller he is given and is brought back to the ship. T'Pol and Crewman Cutler have to wake Doctor Phlox from his annual hibernation to deal with it, and the groggy doctor only just manages to prescribe the right remedy.
