1 Low blood levels of calcium may be caused by low levels of protein (albumin) in the blood, because about half of all calcium in the blood is attached to albumin. 2  For this reason, an ionized calcium level (which is not attached to albumin) and a blood albumin level may also be measured.

Then it's time to hike the Manitou Incline. While many hikes in Colorado rise 1,000, 2,000, even 3,000 feet in elevation over 3 to10 miles, the Manitou Incline boasts an 1,800 foot elevation gain in less than a mile. The steps are sometimes knee-high, a few are even higher. The Incline was created in the early 1900s.
