Weed or Wildflower 🎕 Sacramento National Wildlife Refuge

Anyone know what type of flower this is?

We spotted it growing in the gravel in front of the observation platform at the Sacramento National Wildlife Refuge in late-September.

After doing some research, I think it might be a type of willowherb or lessingia.

When I first saw it, I thought it was just an ordinary weed, but upon closer inspection I noticed the little pink flowers.

It just goes to show you that beautiful things can be found growing anywhere and everywhere!

UPDATE:

The helpful folks who run the US Fish and Wildlife, Pacific Southwest Region's Twitter account have replied that this flower is Marsh Aster.
