Alume (Acjachemen: "raising the head in looking upward")[1][2] was a large Acjachemen village located at the foot of Santiago Peak, upstream from the village of Putiidhem ,within what is now O'Neill Regional Park near the Trabuco Adobe, which was built in 1810 as an outpost of Mission San Juan Capistrano.
[6] Juan Crespí noted that "there is a stream in this hollow [Trabuco Creek] with the finest and purest running water we have come upon so far," further writing "we made camp close to a village of the most tractable and friendly heathens we have seen upon the whole way; as soon as we arrived they all came over weaponless to our camp... and have stayed almost the whole day long with us.
[7] Similar to other Acjachemen villages, Alume likely became depleted by the expansion of Mission San Juan Capistrano.
By 1833 over 4,317 native people (1,689 adults and 2,628 children), largely from surrounding Acjachemen villages, had been baptized at the mission.
That same year it was recorded that 3,158 had died in that same period, indicating the disastrous effects of the mission system on native people's lives.
