This stately memorial is just a short walk from nearby Byers Lake Campground, or you can park directly at the memorial. It can be tough to find the right footpath here from the campground, so I personally think it's easiest to walk along the campground access road and take a clear side path to reach the memorial, then find the footpath back to the campground from here.
The 20-foot concrete panels represent the different branches of the military, and the statue represents two Alaska Territorial Guards — a group of Indigenous and immigrant soldiers who defended Alaska, which was not yet a state, in response to the Japanese invasion in 1942. 
On a clear day, you can also get amazing views of Denali from here.
