From the air looking upstream. The old
stream meander that made the opportunity for a bridge to form is clearly
visible. The easy breaking through of the thin ridge is easily visualized.
It would be many millennia before this sturdy bridge would collapse.
Something else would eliminate this magnificient
structure.
In the early 1960's road maps began to
show Gregory Bridge up on the plateau above, well away from the waters
of future Lake Powell where earlier maps properly showed it. However,
the top pool level of Lake Powell, 3710' is well above the top of Gregory
Bridge. |
