Besides the unexplained lights flickering off and on, employees also report cold spots and chilly drafts in rooms with no ventilation.

6. NORTH PORTLAND LIBRARY

A few years ago, this former Carnegie library at 512 N Killingsworth Street was renovated and security cameras were installed throughout. Every few seconds the view from a different one of the cameras appears on the video monitor behind the front desk. Soon after renovation, librarians watching the monitor saw an old man seated alone in the enormous second-floor meeting hall. The image only appears for a few seconds before the system cycles to the view from the next camera, but it shows enough to panic the staff. Still, every time they stampede upstairs to find the trespasser, they find the meeting room locked and empty.

Supposedly, the camera still shows the old man upstairs, but only occasionally, despite an increased effort to keep the room locked.

7. CATHEDRAL PARK

This park gets its name from the towering gothic arches that carry the Saint John's Bridge overhead. These arches march through the park, creating a sort-of cathedral effect. It's a wide-open park of lawns and play equipment, but not long ago it was a wasteland of briar thickets and hobo jungles, warehouses, and old wharves.

For most of the twentieth century local kids earned summer money by picking strawberries, raspberries, and boysenberries on outlying farms. These kids would wait, early in the morning, on street corners where the "Berry Buses" would pick them up. The buses took them to work and brought them home.

In the 1930s a young girl was kidnapped while waiting for the Berry Bus in North Portland. According to local legend, she was taken to the bushes below the north end of the Saint John's Bridge, tortured, and killed. Even now that Cathedral Park is a nice garden and hosts a summer jazz festival, nearby residents say you can still hear that one girl screaming in the park on warm summer nights.

8. SAUVIE ISLAND

Once called Wappato Island, this island between the Columbia River, the Willamette River, and the Multnomah Channel was home to a village of some fifty thousand members of the Multnomah tribe. Even before Portland was founded, smallpox brought by early explorers had left the island a deserted ruin of rotting huts and scarred survivors.

Today you can still find arrowheads scattered along the Columbia River beaches. Early morning joggers and late-evening walkers also report almost identical encounters with a naked Multnomah youth. The adolescent boy walks along the waterline and doesn't seem aware of anything except the river and the sand.

More recently, so many cremated nudists have been spread on "clothing optional" Collins Beach that most level areas above the tide line are layered in the telltale crunchy white grit of crushed bone.
