Although the well-known sugar maple only grows in the eastern U.S., a variety of Pacific Northwest trees are also potential sources of sap for making syrup.
Drill a 3/4-inch diameter hole about 1" to 2" deep in a likely tree and insert a tight-fitting plastic or wooden tube. Leave a small "collection space" between the end of the tube and the back and the back of the hole.

Cover hanging containers to keep precipitation, dirt, and bark from falling in.
You'll hit some "dry" trees, but occasionally you'll also hit a "gusher" that yields a gallon or more in one day.
Hang a pail or other container under the tree tap.
The collected sap is condensed by steaming at 170°F in a large cast iron pot.
