What Carbon County Historical Society does
Mission
The mission of the Carbon County Historical Society and museum is to preserve andcommunicate the history of the carbon county area.
As stated on its FY2024 Form 990.
Program
Operation of the county museum. In 2024 there were approximately 2,400 visitors that attended lectures, toured the museum, and worked on research in the archives. As part of the ongoing operations, historical collections were received and catalogued, and archives maintained.
The first program described on its most recent Form 990, which lists programs largest first by expense.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars.
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2020 28% · 2024 4%. Grants only. Government contracts and fees sit inside program revenue.
70% of CARBON COUNTY HISTORICAL SOCIETY’s revenue is contributions — more donation-reliant than the typical peer (64% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 3 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base narrowed from 3 funders to 1 funder, grant income rose $10k → $15k.
1 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 88% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $4k from one payer (the payer's own filing calls it a related party, largest Johnson Family Foundation). These are real filings, and they are not money CARBON COUNTY HISTORICAL SOCIETY raised.
From the IRS filings of CARBON COUNTY HISTORICAL SOCIETY’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
CARBON COUNTY HISTORICAL SOCIETY leans on a few funders — its largest provides 88% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
98% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund CARBON COUNTY HISTORICAL SOCIETY.
Largest funder’s share by year: 2017 73% · 2018 100% · 2019 100% · 2020 100% · 2021 54% · 2023 100% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
88% of CARBON COUNTY HISTORICAL SOCIETY's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $17k that is directly attributable, 100% of it comes from Montana funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $128k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
