Task #22: Visit all the National Parks in the continental United States - UPDATE #4

I've made progress!! Knocked 5 more parks off the list. See below! I've made a lot of progress since 2008 when I made this original list. Went from 31 parks needed to 16 in only 6 years.

Here's info on the original post which explains why there might be some missing. And the second post here. And the most recent post here.
