Thanks! It's OK, these are irregular rustic stone steps on dirt, very common all over the mountains of Colorado.
https://wiki.openstreetmap.org/wiki/Tag:highway=steps has 2 similar photos : one is all stone steps, the other is wood steps on dirt. This one in Pagosa Springs is stone steps on dirt. I tagged it like the examples. Also, Up/Down doesn't make sense here because you can go either up or down these steps.
