The government's dietary recommendations are 200 IUs a day up to age 50, 400 IUs to age 70, and 600 IUs over 70. But many experts believe that these recommendations are far too low to maintain healthful vitamin D levels.
Crater Lake National Park. Crater Lake National Park is a United States National Park located in southern Oregon. Established in 1902, Crater Lake National Park is the fifth-oldest national park in the U.S. and the only national park in Oregon. The park encompasses the caldera of Crater Lake, a remnant of a destroyed volcano, Mount Mazama, and the surrounding hills and forests.
After a camping feast, we packed our backpack with snacks, sunscreen, swimsuits and bug spray (important) and set out for a hike. Since it was early in the season for summer activities at Crater Lake, many of the trails were still closed due to snow and unsafe conditions. We decided a trek down to the water was necessary, and got on Cleetwood Cove Trail, a 2.2-mile hike round trip.
