IN 2024, FOR THE 12TH ANNUAL DINO SHINDIG WE HOSTED 748 PEOPLE OVER A THREE DAY PERIOD. SINCE 2013, THE SHINDIG HAS SERVED 14,400 PEOPLE. DONOR RESTRICTED INCOME INCLUDED THE JUNIOR SCIENTIST PROGRAM ($3,620) WITH EXPENSES. APPROXIMATELY 20,809 PEOPLE WERE REACHED THROUGH EDUCATIONAL PROGRAMMING, INCLUDING 1,039 ON-SITE, 3,851 OFF-SITE, AND 15,199 THROUGH VIRTUAL PROGRAMMING.

  • MUSEUM DEVELOPMENT - EXHIBITIONS AT THE CARTER COUNTY MUSEUM FOLLOW THE NARRATIVE OF THE LANDSCAPE THROUGH THE DEEP PAST AND ITS EVOLVING RELATIONSHIP BETWEEN A DIVERSE GROUP OF INDIGENOUS AND RANCHING CULTURES. OUR COLLECTIONS WERE AMASSED OVER AN 80+ YEAR PERIOD AND REPRESENT 90 MILLION YEARS OF HISTORY AND PREHISTORY OF SOUTHEASTERN MONTANA AND CARTER COUNTY. CONTRIBUTIONS TO THIS PROGRAM SERVICE INCLUDE THE ARTIST IN RESIDENCE PROGRAM ($400) AND THE SCOPE PROGRAM ($6,000 INCOME, $9,356.10 EXPENSES). THE MUSEUM CONTINUED THE BIG SKY SEAWAY EXHIBITION, WHICH INCURRED EXPENSES OF $24,453.94, AND INSTALLED A COMMUNITY GARDEN WITH REIMAGINING RURAL GRANT FUNDS ($2,000). WE ALSO CONDUCTED AN ENERGY DESIGN STUDY ON THE PROPOSED MUSEUM RENOVATION AND EXPANSION THROUGH A $20,000 GRANT FROM SOUTHEAST ELECTRIC COOPERATIVE. A TOTAL OF 5,808 PEOPLE ATTENDED THE MUSEUM IN 2024, WHICH WAS AN INCREASE OF 5.5% FROM 2023.

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.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

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.
