Attention geology junkies, I've got questions here.
These gravel bars separated by a sharp notch about 25 years at the bottom and 35-40 years at the top do not appear to be old Manly Lake beachfront property. Both gravel bars are flat on the top, lose elevation almost in a straight arrow down south-southwest at about a 6-10% grade. The notch does not appear to be cut by a stream flow and the stream bed is clearly along the west, bypasses the notch and ends up in what looks like a drainage catchment basin at the south end of the second gravel bar. It got too dark for me to scamper way down to the end of the second gravel bar to explore the whitish colored basin. I hope to do this my next trip out.
So I have no idea how this anomaly was formed, why it is in this location in this condition? Any theories are sure welcomed here.
In spite of the strong cold wind, I certainly enjoy the light show Mother Nature displayed against the sky, clouds, mountains, and highway. The notch in the gravel bars is easy to miss because usually when driving this area one is looking ahead rather than sideways. I've driven this road at least twenty times and never noticed it before.
