We hopped across the border this afternoon to Colorado (and time traveled to Mountain Time). Here is the sign for Picture Canyon under a cloud-speckled blue sky!
This sign points the way to more prairie! (Or, you know, the trail to the petroglyphs. )
Great rocks and lichens along the trail.
Just a hint of green spring on this tiny tough little bluestem!
This rock was very rectangular.
The chollas here were less sad than the Black Mesa ones. Maybe because this is an arroyo?
The sandstone cliffs were very tall but also a nice cooler microclimate!
A series of vertical line petroglyphs higher up in an eroded hollow area. There is another line through them so they almost look like fish ribs.
A human figure petroglyph!
The horse petroglyph was my favorite!
The horse petroglyph with Briar for scale.
Mom looked at holes in the rocks but didn’t see anyone home. I did hear and see some kestrels flying nearby and heard a Canyon Wren singing though!
These petroglyphs seem to show a horse on the left and two tipis (?). Without more signs it was hard for me to tell what were petroglyphs vs vandalism but most vandalism seemed to be names and initials.
This disk-shaped erosion in the sandstone was neat.
The cooler microclimate with shade and a different rock nearby resulted in some foliose lichens!
We found a flower blooming that wasn’t skunk bush sumac! Mom identified this as Ribes leptanthum, trumpet gooseberry. It has lovely flowers and very friendly spines too. We didn’t see many insects out on either species though, presumably because it’s such a drought.
Little sprinkles to the west (if it even hit the ground) on our way back to camp!
A multipurpose state line sign on a county road.
On the way back we stopped to see the replica of a brontosaurus femur that the park brochures note is on private property by the roadside. It is for commemoration of many dinosaur fossils found on the private property.
