You guys have penchant for answering the riddles we pose on social media faster than greased lightning, so we thought we would crank up the difficulty level. And in honor of the month of Halloween, our challenges will all have a creep factor.

In the case of today’s challenge, that factor is the haunting voice speaking to us from ages  long past. But this recording isn’t just creepy, it’s also historically significant!

The first person who can comment what this sound is and why it’s important will have their choice of one of three prizes: a 3D printed Allosaurus skull, The Companion book to our Giant Screen film Nation Parks Adventure 3D, or the beautiful companion book to our special exhibit Art and the Animal

And while we’re talking about creepy things, don’t forget that the coolest Halloween party in Houston will be happening here at HMNS on October 29! There are a limited number of tickets available, so make sure to to go to hmns.org to secure tickets. Group rates are available.

Also, HMNS Sugarland has cooked up an exciting collaboration with Houston Zombie Walk called the Museum of Madness and Mayhem Haunted House, which will be scaring the pants off of anyone 15 years old and up on the last two Fridays of October: the 21st and 28th.

And for the kids, HMNS Sugarland is also hosting the Magical Maze and Goosebumps Haunted House the last two Saturdays in October, the 22nd and 29th.
