Ice falls near Huixian Xigou, Henan Province

It was nice to get off the great loess plain for awhile, just to get out of the smog.

Sunrise over Huang He (the Yellow River) on the shortest day of the year.

Huixian Xigou is the first small village I have seen in China. I don't think more than a few hundred people live here. Every other "small town" I have been to has a population in the millions.

The blue sky is something else I haven't seen here.

I was expecting to see eroded mounds of loess, but was pleasantly surprised to find that the place really is sort of a mountain--in the same way that Hamilton is on a "mountain".

The escarpment alternates between shales and carbonates (the cliffs) with a little karsting at the top to make things interesting.

Ripple marks were quite common on some of the harder surfaces, but there were no trace fossils that I could see.

Persimmons, still on the tree

Real mountain living


Groundwater seeping out of bedrock along cliff exposures freezes into icicles.

With some people for scale.

Anita's mad posing skills.

She doesn't see ice very often.
