In the Julian Bashir, Secret Agent holoprogram, Julian Bashir fell out of a dirigible over Iceland. Luckily, he was equipped with a parachute and a submarine was waiting for him. (DS9: "Our Man Bashir")
Background information Edit
At one point during the production of Star Trek, Iceland was considered as a filming location, though this did not come to pass.  For Star Trek Into Darkness, the backdrop of the planetoid where Carol Marcus and Leonard McCoy examined an advanced long-range torpedo was filmed in Iceland.
