    "Someone left the Colorado Plateau cake out, in the rain..."

    LOL.

    Anyhoo, thanks for this awesome Bryce tour (another place I've yet to visit) & the introduction of the term headward erosion.  I'm not particularly clear on how this works--can't visualize it--does this mean that water pools at a head & the swirling action erodes away, rather than a unidirectional flowing erosive action?

      for your comments, and, yes, do, please, get to see this fantastic setting in person. It's high up there in the loftiest elevation of the Colorado Plateau, so huffing and puffing is okay. Fainting isn't. Anyway, headward erosion is a common process in parts of the Plateau country, and especially plays a key role in the Grand Canyon's forming, though NOT from the eastern sector, rather from the west (a drainage that literally chewed its way across an uncut plateau, invigorated by its volume and the direction of tilt across the planed surface. Technically, headward erosion Headward erosion is a process by which a stream or river becomes longer and more pronounced (wider). The head of the body of water erodes more quickly as the rain erodes rock at the head. As more rain falls, the rock is eroded more, and the river cuts back at the. When it cuts, it erodes rock, and so the river's length is extended. What happened in the Bryce Canyon-Paria Canyon sector is really all about this kind of erosion, and not just typical weathering. If you want to know more, kiddo, please email me at my profile's email account and I'll be more than happy to "learn" ya. Thanks, again, for posting your appreciative remarks. Most kind!
