NATIONAL PARK MYSTERY PHOTO

A total of 16 Mystery Photo quizzes were posted during 2009. This quiz is intended to be a monthly feature -- and has been since last August -- but we got a late start and didn’t offer the first one until May. We made up for lost time by posting several a month until July when we switched to the once-a-month schedule we’ll now try to maintain in 2010.

#1 Wow – This is One Big Boulder!
#2 Where In the National Park System Does Puck Reside?
#3 It's All In the Patterns
#4 What Cabin Is that Yonder?
#5 Which Way Does The Wind Blow?
#6 A Movie-Goers Special
#7 Who Was This Maiden?
#8 Well, It's Kinda Oval
#9 What Sort of Reviewing Stand Might This Be?
#10 Name that Location
#11 And What Room Might This Be?
#12 Lots of Water Out There
#13 Beam Me Up Scotty!
#14 You Might Know What This Is, But Where is It?
#15 What's She Smiling About?
#16 Something Curious This Way Came

NATIONAL PARK MYSTERY SPOT

We posted six Mystery Spot quizzes this past year. Readers had a lot of fun with them, so we’re going to continue offering one a month.

#1 Joe DiMaggio and Babe Ruth Used It
#2 You Walk Around, I’ll Walk In
#3 Do the Math
#4 Standing Tall In the Middle
#5 A Jenny May Take You There
#6 You Might hear It Before You See It

NATIONAL PARK MYSTERY PLANT

Only four Mystery Plant brain teasers were posted in 2009, but we’re planning to make it a regular monthly feature beginning this month.

#1 Will This “Lime-Green Cancer” Derail Everglades Restoration?
#2 There’s a Good Reason They Call This Thing the “Death Apple”
#3 It’s Toxic, and Livestock Producers Hate It
#4 This “Tree from Hell” Smells Like Rancid Peanut Butter
