Very faint green to white crystal grains showing cleavages and a bright orange color under SW UV. Just about the entire area between the green arrows is Walstromite. At the blue arrow in a bit of yellow Fresnoite.

Walstromite is named in honor of Robert E. Walstrom (1937-2022), who discovered it while prospecting for barium. From Mindat: He has 12 minerals new to science to his credit, already published (2008), with more in the works. I never knew Bob real well, but from what I gather he was an amazing field collector as well as a great mineralogist.

A good article titled "Barium Minerals of the Sanbornite Deposits of Fresno Co., California" was published on the Mineralogical Record Axis articale V1 n8 (2005) click here.
