👆 This should be the number of sites we get when we use uscrn.get_data() (for a time period that the currently reported operational status is accurate for).
Sites with “closing” in the past are not marked as operational (good).

There is a range of elevations.

Most of the sites that are high above sea-level are in NM/CO/UT/AZ. CO/WY/UT/NM/NV are the top five highest states overall, in that order.

Some sites don’t have a WBAN (but do have a station ID). Presumably these sites aren’t included in the data archives.
