Description
Mount Sylvania is a million-year-old shield volcano in Southwest Portland and Lake Oswego's Mountain Park neighborhood. It is one of three shield volcanoes in the Boring Volcanic Field, the others being Highland Butte (southeast of Oregon City) and Larch Mountain in the Columbia Gorge.
Nansen Summit Park is at the top of the volcano and is just shy of 1,000 feet in elevation. There are expensive homes all around, but the park offers views south to the Tualatin Valley and the West Hills. There’s a weather station here and a radio telemetry antenna as well as a couple of benches.
Fridtjof Nansen was a Norwegian polar explorer and diplomat who received the Nobel Peace Prize.
