Kelsey Peak (10,373 ft) is located along the Oquirrh Mountains, the large mountain range just West of SLC. It's not the highest summit in the range (Flat Top Mountain is the high point), yet hiking to the peak is very rewarding. You can knock out three peaks in one morning - Butterfield Peaks, White Pine Peak (aka Wans Peak on some older maps), and Kelsey Peak. If you had enough time and energy you could make it all the way to Lowe Peak, or if you set your goals really high you could even complete the Oquirrh Ridgeline Ascension Trail (the whole ridge line point to point)!
Fool Creek Peak (9,712 ft) is the highest summit in the Canyon Mountain Range in central Utah, and ranks #20 on the Utah Prominence List with 3,712 ft. I bet everyone has seen this peak, but nobody knows the name as you drive by it heading south on I-15 in Scipio, UT. This is one of the reasons I just had to hike this peak - every time I would drive on I-15 I said to myself "One day I'll hike to that peak!" So I did.
Lower Calf Creek Falls is one of the most popular trails near Escalante, UT and in Grand Staircase-Escalante National Monument.
Little Death Hollow is a slot canyon in the northeast corner of Grand Staircase-Escalante National Monument in an area called the Circle Cliffs. Not to be confused with "Death Hollow" near Boulder, UT, Little Death Hollow offers a 4 mile slot canyon that, when dry, offers few obstacles, and beautiful high red sandstone cliffs which deepens and narrows as you continue down canyon.
