 In addition to administering the mission at San Borja, over the next five years Linck undertook a series of exploring expeditions to scout future mission sites and resolve geographical puzzles.His travels included journeys to the peninsula's west coast, to Isla Angel de la Guarda, and to the north in an ambitious but failed attempt to reach the lower Colorado River and settle once and for all the geographical question of whether Baja California was an island.When the Jesuits were expelled from Baja California in 1768, Linck returned to Bohemia, where he died in 1797.
