It is located near the radio tower on Kenosha pass, maybe 200 yards away. It's about 12 feet tall, made of fiberglass painted black except for panels on the sides that appear to be a way to measure the contents. There are a couple of threaded pipe type fittings, one near the very bottom. The ring on top is made of galvanized pipe and sheet metal. It’s bolted to a cement base and appears to have been there quite some time.
It certainly could be some sort of a solar water heater but for whom or what?
Perhaps it is a marker beacon for commercial airlines to follow on their glide path into Denver? Seems like most of eastbound jets go right over Kenosha Pass.
The outer marker is normally located 7.2 km (3.9 nm) from the threshold except that, where this distance is not practicable, the outer marker may be located between 6.5 and 11.1 km (3.5 and 6 nm) from the threshold. The purpose of this beacon is to provide height, distance and equipment functioning checks to aircraft on intermediate and final approach. In the United States, an NDB is often combined with the outer marker beacon in the ILS approach (called a Locator Outer Marker, or LOM); in Canada, low-powered NDBs have replaced marker beacons entirely.
