I'd like to locate the US National Park Service basemap, ideally as a WMS or WMTS to use in a leaflet map.
While browsing the NPS docs: https://www.nps.gov/maps/tools/npmap.js/api/#wms I am repeatedly met with broken links of working examples. An on top of that, the docs keep using a current weather WMS in their documentation (example: http://nowcoast.noaa.gov/wms/com.esri.wms.Esrimap/obs
However, it seems that this basemap does exist because the NPS is using it as their actual basemap in all their examples:
So where can I find the basemap itself?
