I was snooping around Land's End a couple weeks ago and noticed that the octagon house is now vacant. When I worked at the VA someone was living there. I believe I went on a history hike and heard that she was a relative of the last lookout.
It was fun to poke around, I'll post my photos on the Flickr group. If only I had the nerve to climb a tree I could have taken some neat shots of the inside.
I found this 1931 newspaper article about the lookout at the time, Larsen: http://news.google.com/newspapers?nid=950&dat=19310224&id=PpoLAAAAIBAJ&sjid=kFQDAAAAIBAJ&pg=5285,2589881
Also found this document stating the building is not considered historically significant: http://220.127.116.11/search?q=cache:TWIFBnR3QrsJ:www.hscl.cr.nps.gov/insidenps/report.asp?STATE=&PARK=&STRUCTURE=&SORT=2&RECORDNO=24638+marine+exchange+point+lobos+octagon&cd=9&hl=en&ct=clnk&gl=us
Does anyone know more about the family or NPS plans for the building?
