The Wasatch Mountains offer plenty of fascinating tales and mystery, even in the 21st century.

They're fodder for speculation related to the Book of Mormon and stories of Bigfoot, lost gold mines, Indian maidens and huge grizzly bears. Adding to the sense of mystery, oak brush and trees dominate the lower elevations of the mountains and make for lots of hiding places.

Here are some local mountain legends:

Bigfoot — Only 10 of the 50 states have more reported sightings of "Sasquatch" than Utah. Many of these purported experiences are reported in or along the Wasatch Mountains. From the mountains east of Ogden and North Ogden to the foothills of South Weber and Francis Peak, sightings date back almost 25 years.

Gadianton Robbers — Did these shady characters, mentioned in the Books of Helaman, Third Nephi and Mormon in the Book of Mormon, reside in the Wasatch Mountains?

Brigham Young seemed to think so and all but said the mountains were haunted. Some of the aforementioned bad guys would apparently rob, murder and plunder among the Nephites and then hide in the Wasatch Mountains.

"There are scores of evil spirits here, spirits of the old Gadianton robbers, some of whom inhabited these mountains and used to go into the south and afflict the Nephites. There are millions of these spirits in the mountains, and they are ready to make us covetous, if they can; they are ready to lead astray every man and woman that wishes to be a Latter-day Saint." (Deseret News, March 20, 1861, from a talk given in the Tabernacle on Jan. 20, 1861.)

Grizzly bears — Huge grizzlies used to inhabit the Wasatch, and as recently as the 1920s, two of them still roamed the mountains. One was killed on Mount Nebo about 80 years ago. The more famous bear — "Old Ephraim" — was shot by a sheep rancher on Aug. 22, 1923. Old Eph was reputed to be about 1,600 pounds and 9 feet tall.

Indian maidens — If you gaze at Mount Timpanogos heading northbound on I-15, near Nephi, it doesn't take a lot of imagination to visualize the shape of mountain skyline as a woman lying down. The story goes that an Indian maiden, Utana, committed suicide by throwing herself off the mountain in Romeo-and-Juliet fashion, after her true love, Red Eagle, died from injuries in a bear attack.

The Great Spirit supposedly melded the hearts of the two dead lovers to produce the Great Heart of Timpanogos, a stalactite in Timpanogos Cave.
