Yes you can. People leave all sorts of items at memorial site.
How long was the hike
Yes. There are multiple places to leave flowers. At fatality site, at tje over look, at the trail head, or at each person's individual plaque.
Yes you can
It is a very good idea to leave flowers!
Yes you can. They do ask that you stay outside the memorial circle at the bottom of the hike tho.
The actual memorial sites are a nice long hike from where you park, but there was all sorts of stuff left behind to honor these men. You can contact the Parks department to verify, but I'm sure it's okay as long as it's not litter
