It's time for our monthly park news round-up. This time, there are two new park units, a new study shares how some people really are "mosquito magnets," and some new science shows that Yosemite is much younger than we previously thought it was. 

Today's show was sponsored by L.L.Bean, follow the hashtag #beanoutsider, and visit LLBean.com to find great gear for exploring the National Parks. 

And by Campendium. Find listings and reviews for thousands of campsites for your next national park adventure at campendium.com.
