How this study was read

The method in full
  1. What is written

    The scholarly Sharp catalogue dates Yellowstone’s canvas to about 1907 and proposes a relationship to a larger Blackfeet-region landscape. Its description of flowers prompts a broad seasonal comparison, not a painting date.

  2. Records of those days

    • Columbia Falls 5 SW, USC00241919Western regional context. Three complete May–September precipitation seasons; 40 complete same-station seasons retained for comparison. The scene is not located at this station.
    • Browning and Babb 6 NEEastern candidates were checked. Gaps prevent a complete three-year seasonal comparison; their exclusions remain in the linked data.

    Not found or not yet searched

    • No exact viewpoint, painting day, dated sketch or independent explanation of the circa date has been established.
    • The larger canvas’s inscription is retrospective and belongs to another object; the hotel is not identified here.
    • No local sky, snow-cover or flower phenology observation is inferred from the western station. Historical instrument exposures are unverified.
  3. Each claim tested

    • Does the park’s establishment in 1910 disprove the circa-1907 date? No. The title alone does not date execution. The related canvas carries a later inscription; neither it nor park history proves when the Yellowstone canvas was painted.
    • What moisture context survives around the approximate date? 1906: 281.8 mm; 1907: 326.3 mm; 1908: 542.9 mm. These are recorded measurable precipitation sums at Columbia Falls for May–September, with trace amounts unquantified. The three years are examples around the catalogue date.
    • Do the flowers identify a wet year or a painted day? No. Seasonal precipitation at a western station cannot establish conditions at an unlocated mountain scene or date the flowers.
  4. Verdict

    A possible relationship between two paintings helps frame the place question. Regional records supply context; the painted weather and exact date remain unknown.

    • UnknownWeather depicted in the Yellowstone canvas A circa date, broad region and flowers do not connect the picture to a particular observation.
    • UnknownWhat Sharp changed between the two views The catalogue proposes a relationship, but no dated sequence or field-to-studio account has been established.

What this cannot tell you. May–September 1906–1908 is an illustrative comparison, not a documented execution interval or the full uncertainty range of ca. 1907. Station distances are to a named modern East Glacier inventory point, not to an identified viewpoint. Across-divide weather can differ substantially. Ranks describe complete archived seasons, not a homogeneous climate normal. Traces are counted but not assigned a measurable amount; missing data stay missing. No image is reproduced because an open licence or written reproduction permission has not been established.

Step 1 · The picture and its date

A small canvas linked to another view

The Buffalo Bill Center of the West’s scholarly Sharp catalogue identifies Yellowstone Art Museum’s Glacier Park, VS1993.124, as an oil on canvas, 12¼ × 18 inches, dated about 1907. It records a signature at lower right, but no dated inscription for this object. The public record does not explain the basis of the approximate date or when the title was assigned. The catalogue describes a road and a field of flowers and proposes that the canvas is a study related to a larger finished landscape. That relationship is a scholarly interpretation, not a dated account of the painting sessions.

The larger work is Glacier Park, Blackfeet Reservation, Montana, Eiteljorg Museum, 1989.3.86. The catalogue transcribes Sharp’s retrospective inscription, dated August 1950, saying that the picture preceded a nearby hotel. That inscription belongs to the Eiteljorg canvas, not the Yellowstone canvas. The hotel and the precise viewpoints have not been established here.

Glacier National Park was established on 11 May 1910, after the approximate catalogue date. The title alone does not settle when the Yellowstone painting was made; the later inscription on the related work does not establish the Yellowstone canvas’s date.

Sharp’s Montana activity also extended beyond Crow Agency. The Couse-Sharp Historic Site places his winters there from 1899; the Sharp catalogue’s signed and dated Powder Bull – Blackfoot documents Blackfeet-region work in 1902. Neither source supplies a 1907 visit for this landscape. Crow Agency weather would not resolve a scene associated with the Glacier region.

The comparison window is Nephos’s choice: May–September in 1906, 1907 and 1908, prompted by the catalogue’s description of flowers. These are illustrative neighbouring years around an approximate date, not the earliest and latest possible years or a documented flowering season. No plant identification, snow condition or cloud type is inferred.

Step 2 · A regional record

The neighbouring years are not interchangeable

At Columbia Falls 5 SW, recorded measurable precipitation for May–September is 1906: 281.8 mm; 1907: 326.3 mm; 1908: 542.9 mm. The last of these is the wettest of the 40 complete seasons retained from this file, which run from 1896 to 1948, with gaps. Choosing a different year around the catalogue date changes the regional comparison substantially. The flowers do not select one of those years.

Each total requires all 153 days to be usable. Trace precipitation is counted separately: the archive records no measurable amount for it, so the sums are not exact totals including traces. A missing value, a quality flag or a presumed-zero flag prevents a complete total. Historical gauge exposures have not been verified; the ranks describe the archived series, not a homogeneous climate normal.

Step 3 · Check the distance and gaps

The usable record is on the western side

Browning and Babb 6 NE are eastern candidates, but their gaps prevent a complete comparison for these three seasons. Columbia Falls is the nearer of the screened western records with complete precipitation coverage in all three years; Kalispell provides another complete western record. A record across the Continental Divide cannot stand in for the unlocated Blackfeet-region scene.

The distances below are straight-line distances from the archive’s station coordinates to its East Glacier station inventory point. This is a geographic reference, not Sharp’s identified viewpoint. Actual station-to-picture distances and historical instrument locations remain unknown. Other screened Glacier-area files start too late; the linked data retain their coverage and rejection reasons.

Columbia Falls has a complete May–September temperature mean only for 1907 among the three selected years: 55.7 °F (13.1 °C), averaging each day’s high–low midpoint. Incomplete years receive no seasonal mean. This thermometer context cannot test mountain snow or the painted sky.

Step 4 · What remains a question

Flowers do not date the weather

The catalogue’s proposed connection between two pictures helps frame the place and making questions. It does not establish an outdoor session, a sequence of revisions or a painted day. The surviving western record shows how much the seasonal context varies between nearby years; it cannot establish moisture at the scene, explain the flowers or prove what Sharp changed.

For a docent conversation, keep three kinds of evidence separate: the catalogue’s approximate date, the artist’s later words on another painting, and the weather station’s measurements. The most useful next evidence would be an object-file inscription, label or dated sketch tying VS1993.124 to a specific place and visit.
