About This Trip

In Flagstaff, Arizona, step into the splendor of a night sky few places on Earth can rival.

Visit the telescope that discovered Pluto, uncover centuries of Indigenous history rooted in the region, and explore an ancient volcanic landscape shaped in part by a meteorite impact.

Itinerary Highlights

  • Grand Canyon National Park
  • Meteor Crater
  • Sunset Crater volcano
  • Wupatki National Monument’s ancestral Pueblo sites
  • An evening at Lowell Observatory, including the Pluto Discovery Telescope and the open-air Dark Sky Planetarium

Vanessa Alarcon

Astronomical Observer at Griffith Observatory

Vanessa Alarcon began working at Griffith Observatory in 2015 as a part-time Telescope Demonstrator and became the full-time Astronomical Observer in 2023.

As the Astronomical Observer, Vanessa is the steward to all telescopes and observational instruments at Griffith Observatory, including the optics in the Gottlieb Transit Corridor. She is also co-host of Griffith Observatory’s monthly Sky Report. In 2024, she pioneered the Observatory’s livestream broadcasting of the total solar eclipse.

Vanessa is an experienced dark-sky chaser who has led astronomy trips throughout the United States, including Flagstaff, Death Valley, and Zion National Park, to observe stars, meteor showers, and celestial events. She also planned and led a two-week trip to Casper, Wyoming for the 2017 total solar eclipse.

This morning, we depart Flagstaff for a guided excursion to Grand Canyon National Park, exploring some of the most iconic viewpoints along the South Rim.

Our journey includes a stop at the historic Desert View Watchtower, where sweeping panoramic vistas stretch across the canyon and the Colorado River corridor. In addition to its architectural significance, the Watchtower offers rich cultural context tied to Indigenous heritage and early park history.

Midday, we’ll pause for lunch at one of the South Rim’s historic lodges or dining venues within Grand Canyon National Park (TBC).

This relaxed break will provide time to recharge, take in the canyon views, and reflect on the morning’s exploration before continuing our scenic rim loop.

A Dark-Sky event is recommended for the evening (schedule and location TBC).

Friday, April 9, 2027

Our first stop is Sunset Crater Volcano National Monument. As we depart Flagstaff, guests will enjoy an engaging talk during the drive, connecting the day’s explorations in astronomy, geology, and cultural history. Topics will include volcanic activity, the region’s Indigenous knowledge systems, and how early peoples used the Sun, Moon, and stars to guide daily life and agricultural practices. 

At Sunset Crater Volcano National Monument, guests will walk among ancient lava flows while observing volcanic processes, landscape evolution, and the interplay between Earth and sky.

Next, we continue to Wupatki National Monument for a curated tour of ancestral Pueblo sites. Here, we’ll explore how celestial cycles influenced architecture, agriculture, and daily life. We will then return to Flagstaff for lunch and a brief rest period.

We conclude the day with a special evening at Lowell Observatory, exploring Flagstaff’s rich legacy of astronomical discovery and its enduring contributions to our understanding of the universe.

Guests will enjoy dinner at the observatory, an up-close look at the historic Pluto Discovery Telescope and Clark Telescope, featured in Signs of Life, a special observing experience and an outdoor planetarium experience beneath Flagstaff’s exceptional dark skies, The evening blends the region’s remarkable scientific heritage and the wonders of the cosmos.

Saturday, April 10, 2027

Guests will travel to Meteor Crater for a behind-the-scenes experience examining impact dynamics, shock metamorphism, ejecta distribution, and the historical role the crater has played in validating impact cratering as a dominant geologic process across the solar system. The site’s influence on Apollo astronaut training and planetary analog research will be discussed within a broader exploration framework. Lunch is available on site. 

After Meteor Crater, guests will visit the USGS Astrogeology Science Center, a public facility renowned for its planetary research. Our group will enjoy a curated experience with expert guides, offering insights and context tailored to our itinerary. Highlights include:

  • Planetary cartography and surface mapping of the Moon, Mars, and other worlds
