Mission

Mammoth Mountain Community Foundation believes that opportunity and access to the Eastern Sierra should be open and inclusive to all. By financially supporting youth academics and athletic programs in the Eastern Sierra, we inspire future generations to love our mountains.

  • Assist children to achieve their academic potential by providing financial support to the existing institutions of the Mammoth Unified School District including new programs, positions, technology, and facility improvements. The Mammoth School District is located in the Eastern Sierra Nevada Mountains of California. The district serves approximately 1,200 students in four schools. In addition, one independent study center is available for education using classroom and virtual methods. Support for the local schools serves to augment state funding and provide for a margin of excelence in education. High School students apply for college scholarships within this program and 20 scholarships were awarded in the amount of $18,750.

    Expenses $387,106 · Grants $264,555

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
