It's located on the side of a small hilltop east of what used to be a town called "Happy Valley", now a sprawl of subdivisions in northern Clackastan (as we urban hipsters refer to Clackamas County).
Here's a brief description of the place, from the Happy Valley historical page:
"From the very beginning the settlers needed a place to bury their dead, and such a place was found near the summit of a neighboring knoll now called "Scouters' Mountain." The first to be laid in it was an unknown man who had arrived in the same wagon train with the Deardorff's and who died in 1852, shortly after reaching the valley."
(My guess is that this guy's name wasn't "Covered Wagon Pioneer" and that Deardorffs or whoever planted him knew that name. But the original grave was probably marked by a wooden plank; that's the best they had at the time. By the time anyone bothered to lug a stone up this hill the old plank - and the poor bastard's name - had long since rotted. So there he is today, nameless forever.)
Anyway, to continue:
"John M. Deardorff donated five acres of his land on the mountain for the cemetery, only one acre of which has actually been used. This is where twenty-seven graves, mostly of the Deardorff's and their relatives, are found in a fenced off area surrounded by a wilderness of tall trees, and adorned by clumps of wild flowers in springtime. Most of the headstones have been restored; a few had to be replaced by newer ones. The first grave is that of the wagon pioneer, the last is that of Edith Guidi, 1932. Twelve of the graves are of children and infants. Prominent, old fashioned headstones mark the resting places of the original pioneers: Christian and Matilda Deardorff, John M. and Rachel Deardorff, John Bennet and Clara Deardorff. The cemetery has been closed since the burial of Edith Guidi. It can be reached by means of a trail leading down from the Boy Scout Lodge on top of the mountain and by another trail from the approach road to the lodge."Mind you, the old lodge is long since gone, and the place has been taken over by the regional government to turn into a natural area and wild land. So James Deardorff and his kin and the nameless guy who barely made the end of the Oregon Trail can sleep quietly on the sunny hill where only my footsteps disturb the song of the juncos and the distant hum of the highway.
