Colorado's parks are the Great Sand Dunes National Park in the San Luis Valley, the Black Canyon of the Gunnison National Park in western Colorado, Rocky Mountain National Park along the Continental Divide, and southwest Colorado's Mesa Verde National Park.
The normal cost is $20 per vehicle in Rocky Mountain National Park, $15 per vehicle in the Black Canyon of the Gunnison park and $10 per vehicle in Mesa Verde. The regular cost in Great Sand Dunes is $3 per person.
Saturday, April 24, is National Junior Ranger Day, when kids can take part in special activities and earn an official Junior Ranger patch.
Most parks also are planning special volunteer events, giveaways and discounts during the week to celebrate the 40th anniversary of Earth Day, April 22.
Mesa Verde, for example, is offering 40 percent off T-shirts made from recycled material, as well as a free pack of Colorado wild flower seeds to each visitor all week.

Summary Author: Rob Ratkowski

Astronomers are frequently asked why we have our observatories on high mountain tops. A big part of looking into deep space has to do with atmospheric transparency and freedom of particulates along with heat that causes blurring. A simple but effective understanding of this 'seeing' is to put a finger at arm’s length in front of the Sun and observe the aureole that’s produced. Held at arm’s length, a finger tip subtends about one half of a degree of sky – nearly the same amount of space that both the Sun and Moon take up. At sea level, observing is often compromised by the build up of heat, dust, moisture, haze, pollution, and aerosols that include ash and even salt. Higher up, there’s less of this to deal with since there’s less atmosphere to peer through. These three photos were taken on the Hawaiian island of Maui at (left to right) Baldwin Beach, Kula and Haleakala Observatory, respectively. The disk of the Sun is completely hidden by my index fingertip at 10,000 ft (about 3,050 m). Note, I can positively verify that my finger didn’t increase in size as a result of the thinner air.
Baldwin Beach: 20.913502,-156.394544
Kula: 20.79222, -156.32694
Haleakala Observatory: 20.70825, -156.256678
