Mystery Plant - Big Bluestem - Sit Spot #926 - August 10, 2021

I  found this short composite flower 

beside one of our walking trails.

It has me puzzled.

 Because it is right next to a mowed path,

 it may have been mowed earlier in the season 

but it is now blooming and only about 30 cm tall. 

Any ideas?
