What is this song and who wrote it? Anyone?

Hi, All! Anyone have any idea where this song came from?


Opal lives in Opal Canyon
Opal lives in a trailer land
Little gray trailer and a good samsticker (?)
Living out there in the desert air

Little round Henry lives there with her
Looking for gold in the sagebrush hills
A pick and a shovel and a metal detector
Ain’t never found nothing prob’ly never will

Ain’t got nothin’
Don’t need nothin’
Everything’s here in the circle of love
Happiness found in an old gray trailer
Sage brush surrounded and the stars above

A calico cat
A one-eared hound dog
Sleeping in the shade of a Joshua tree
Most night moonlight fills (eroyal?)
Lord have mercy ain’t it good to be free


Thanks for your help!

Sure it's called Opal by Dave Stamey from his Tonopah album.
