I came across this site while out exploring. It’s a field and wetland managed for wildlife habitat. Several paths, perhaps a little over 1/2 mile, have been mowed in the tall grass to allow easy walking around the site to explore, learn, and to watch for wildlife. You can also view the spring which is the headwaters of Curtin Creek.
It can be tricky to reach, since the entrance is at the end of NE 72nd Ave, and 72nd Ave can only be turned onto when going west on NE 78th St.
