Hey Pat, I think you climbed Blackjack Mountain (2,006 ft), Orizaba's neighbor, and thought it was Orizaba. There's a large, ugly radio tower on Blackjack.
After kayaking from San Pedro on Friday, it took much of the day to hike across the island to bag this peak. In summer, the mountain is scorched and dry. The summit is home to a large fenced-off radio station which kills the mood and prevents anyone from actually getting 360 degree ocean vistas. The following day I kayaked back across the channel to Palos Verdes.
