Aiming to do the 4 State Challenge this weekend and wondering about water sources in MD. Specifically:

Is there water near either the Cowall Shelter or Pogo campsite? It looks like there is and close to the trail. I'd like to avoid adding additional climbing, if possible.

Is the spigot in Washington Monument Park on/uesable?

Is there a spigot in Gathland Park? If so, where? I recall seeing the big pavillion and the monument at the road crossing but not a water source.

Thank you!
