Punta Colorada and Puerto Gato
If the other day was heaven for bird watchers, today was special for geologists. There’s amazing history of the earth here right in front of your eyes if you are taught how to look.
We approached Isla San Jose at Punta Colorada:
The island is made up of fossilized sand dunes, with all
the shells and critters memorialized in fossils. The stripes on the land tell stories:
We began our “moderate” hike (I know now what that means)
and soon came across fantastic sights.
Here’s an area where the fossilized sand lay underneath a stream which
brought rocks and minerals over the edge.
You can see a waterfall of rock from the sediments the stream brought:
In other places the overlying rock remained as the softer
fossilized sand is eroded by wind:
Our hike took us under huge rock overhangs:
This perfectly formed scallop shell is under a rock layer and buried in a sand layer which is eroding. It will fall soon, and we saw many shells high up on the island:
When we finished our climb, we went back down to the
rocky beach for a walk to a place where large fossils were known to be exposed:
We climbed up above the beach:
Here’s a fossilized whale vertebra buried in the rock:
This crab is called Sally Lightfoot. I need to explore why it has that name. These colors are NOT enhanced—it really is
that vibrant:
There were baby Sally Lightfoot crabs nearby:
These tiny Periwinkle snails were in tidal pools. They’re only about ½ inch across:
Also in a tidal pool was this serpent star:
Finally, after the walk, we went back to the ship and
while we ate lunch, the ship moved to Puerto Gato, a small bay on the
mainland. There were choices of
activities, I chose to go sea kayaking along the coast. It was spectacular:
We returned to the ship in time for dinner, after which there was a show of everyone’s five best photos (which had been turned in earlier). Many were truly wonderful.

Wow, this trip has been spectacular. Creatures and landscapes galore. Great photography , too!
ReplyDeleteGreat trip and great photography. We have seen Sally Lightfoot crabs in several places including the Galapagos where they are (or were 20 years ago) in great numbers.
