Early Development and Federal Authorization

1915 — Informal skiing begins on the Peaks

Ole and Pete Solberg reportedly began recreational skiing on the San Francisco Peaks using handmade skis.

1938 — Forest Service authorizes ski-area construction

The U.S. Forest Service approved construction of a road and ski lodge on federal land in Hart Prairie on the western slope of the Peaks. This marked the beginning of formal ski-area development under federal authorization.

1941 — First major transfer of special-use operations

Control of the ski facilities transferred to private operators Al Grasmoen and Arnal Corporation under the Forest Service special-use framework.

1958–1962 — Lift infrastructure installed

A Poma lift was installed in 1958, followed by a chairlift in 1962, significantly expanding ski operations.

First Major Expansion Era

1969 — Large-scale resort expansion proposed

Snowbowl proposed substantial resort expansion including lodges, restaurants, parking, and expanded ski terrain. Tribal and environmental opposition intensified.

1977–1979 — Forest Service reviews master expansion plan

Snowbowl submitted a formal master development plan seeking:

• New chairlifts

• Expanded trails

• Parking expansion

• Road paving

• Additional ski terrain

The proposal would expand the permitted ski area to approximately 777 acres.

1979 — Forest Service approves expansion

The Forest Service approved major infrastructure improvements under the special-use permit.

Wilson v. Block Era (First Major Tribal Lawsuits)

1979–1980 — Tribes sue over expansion

The Hopi and Navajo Nations filed lawsuits challenging the Forest Service approval, arguing violations of:

• American Indian Religious Freedom Act

• National Historic Preservation Act

• Endangered Species Act

• Wilderness Act

1980 — Forest Service approves road paving

Despite tribal objections, the Forest Service regional supervisor approved paving the access road into Snowbowl.

1983 — Wilson v. Block decided

The D.C. Circuit Court upheld the Forest Service approval in Wilson v. Block, ruling that ski-area expansion did not unlawfully burden Native religious practices under federal law. The U.S. Supreme Court declined review later that year.

This became one of the foundational federal cases involving Native religious claims on federal land.

Snowmaking and Wastewater Expansion Era

1986 — Forest Ski Area Permit Act

Congress enacted the Forest Ski Area Permit Act, formalizing long-term ski-area special-use permits on national forest lands. Snowbowl’s permit became renewable on 40-year terms.

2002 — Snowbowl submits major modernization proposal

Snowbowl proposed:

• Artificial snowmaking

• Use of reclaimed wastewater

• New lifts

• Additional trails

• Terrain expansion

• Lodge and facility upgrades

The stated goals were longer and more reliable ski seasons and expanded recreation capacity.

2004–2005 — Environmental review and FEIS

The Forest Service conducted an Environmental Impact Statement process evaluating snowmaking with reclaimed wastewater from the City of Flagstaff.

2005 — Forest Service approves wastewater snowmaking plan

The Forest Service approved:

• Artificial snowmaking

• Pipeline infrastructure

• Use of treated reclaimed wastewater (“Class A+ reclaimed water”)

• New ski lifts

• Additional ski terrain and facilities

This became the most controversial decision in Snowbowl history.

2005 — City of Flagstaff wastewater agreement

The City of Flagstaff entered agreements to supply reclaimed wastewater for snowmaking operations at Snowbowl. This triggered major political and legal disputes locally and among tribes.

Navajo Nation / RFRA Litigation

2005 — Tribes and environmental groups file federal lawsuit

Plaintiffs included:

• Navajo Nation

• Hopi Tribe

• Havasupai Tribe

• Hualapai Tribe

• White Mountain Apache Tribe

• Yavapai-Apache Nation

• Environmental groups

Claims centered on:

• Religious Freedom Restoration Act (RFRA)

• NEPA

• Health and environmental impacts

• Sacred-site desecration

2006 — Federal district court sides with Forest Service

The District Court upheld the Forest Service approval.

March 2007 — Ninth Circuit panel rules for tribe

A three-judge Ninth Circuit panel overturned the approval, holding that wastewater snowmaking substantially burdened Native religious exercise under RFRA.

August 2008 — En banc Ninth Circuit reverses panel

The full Ninth Circuit reversed the earlier decision and allowed Snowbowl’s reclaimed-water snowmaking project to proceed.

January 2009 — U.S. Supreme Court declines review

The Supreme Court denied certiorari, effectively ending the RFRA challenge and allowing construction to proceed.

Secondary Environmental and Health Litigation

September 2009 — Save the Peaks Coalition files new lawsuit

A new lawsuit challenged:

• Environmental review adequacy

• Human health impacts

• Pharmaceutical/endocrine contaminants in reclaimed water

• Public safety issues

Plaintiffs sought to stop pipeline construction and snowmaking implementation.

2010 — Federal court dismisses environmental challenge

The U.S. District Court rejected the claims and upheld Forest Service approvals.

2011 — Pipeline construction begins

Construction of reclaimed-water infrastructure and snowmaking systems started. Widespread protests followed, including arrests of activists and Indigenous organizers.

2012 — Ninth Circuit again upholds snowmaking

The Ninth Circuit affirmed dismissal of the environmental challenge in Save the Peaks Coalition v. U.S. Forest Service.

Public Nuisance and State-Court Litigation

2010 — Hopi Tribe files Arizona public nuisance lawsuit

The Hopi Tribe sued:

• Arizona Snowbowl

• City of Flagstaff

The suit argued reclaimed-water snowmaking constituted a public nuisance interfering with sacred and ceremonial uses of the Peaks.

2018 — Arizona Court of Appeals revives Hopi claims

The appellate court ruled the Hopi Tribe had sufficiently alleged “special injury” to pursue nuisance claims.

November 2018 — Arizona Supreme Court rules for Snowbowl

In Hopi Tribe v. Arizona Snowbowl Resort Limited Partnership, the Arizona Supreme Court ruled the Tribe lacked the type of special injury required for a public nuisance action.

Continuing Expansion and Modern Development

2010s–2020s — Ongoing infrastructure expansion

Snowbowl continued incremental expansion under Forest Service approvals, including:

• Additional snowmaking coverage

• Lift upgrades

• Summer recreation operations

• Terrain development

• Hospitality expansion

2020s — Continued controversy over sacred-site use

The use of reclaimed wastewater on the Peaks remains controversial among tribes, environmental advocates, and some local residents. Debate continues over:

• Federal land management

• Indigenous religious rights

• Water use in arid climates

• Long-term ecological impacts
