Our location is registered as 'Pleasant Valley Victory Through Faith Center' where one of the charity functions is teaching ham radio, so ham visitors are welcome. The property layout is pretty clear from satellite images.

Mountains are Simcoes to the north, Cascades 70 miles west, Goodnoe hills 7 miles south, but the distances provide good take-off angles in all directions. I can see the lights glow from Yakima and Sunnyside and sometimes Tri Cities. Unobstructed view of the Clark Belt from horizon to horizon.

VHF propagation is good. I have worked Hermiston, Bend, Salem, Yakima, Portland and Goldendale repeaters with just a handie-talkie and rubber duckie whip. There is very little local ham activity on 2 meters. This is location is remote and off-grid so it's very radio quiet and a great location for HF and contests such as Salmon Run. An existing vertical or dipole may be available if I'm not operating. - Doug K7EVI

Driving directions: Best route is Bickleton Highway to Old Mountain Road to Holter Road.
Badger Gulch Road is okay but it destroys tires.
Do not use Box Canyon Road since it's impassable. Don't let your GPS take you to Box Canyon Rd.

Restrictions: Get prior permission from Doug K7EVI for private property access.
No hunting, alcohol, drugs, open fires, no smoking.

Along Washington's southern border near Goldendale, the bluffs above the Columbia River offer good bare operating locations. One site in particular is a former AT&T microwave site among the Windy Flats (good name) wind farm, high above the crossing between Maryhill and Biggs Junction. This is a prime candidate for activating the WA side of CN95.

A hilltop site directly north of the Biggs Junction Columbia River Bridge on the WA side. It's an old AT&T microwave site on the bluff overlooking the river, with a great view to the south and east.

The facility itself is gated but a convenient parking pull-out is right there. The road has open public access to here but it is signposted "private" immediately beyond. This spot is surrounded by numerous wind generators and a cellphone tower is very close.

Very poor radio propagation in all directions.

My hope was to shoot east along the river into the Tri-Cities from the far side of the CN95 - DN05 grid line border. And I was hoping some sort of signal path to Portland could be made, but to no avail. You really need explore the nearby bluffs for altitude and good takeoff angles.

Roosevelt is on the Washington side of the river. There is a lovely green park nearby, a favorite spot for sailboard and kite surfers on the constantly windy river gorge.

A very scenic location with very poor radio propagation and considerable noise from power lines.

This location is at the CN85 - CN95 grid line. I hoped to reach Portland using the Columbia River gorge valley, but no contacts were made.

However, the consolation prize is to watch osprey and turkey vultures fishing for salmon in the outflow. This is an incredible spot for bird watching.
