Sanskrit (& Pali?) inscriptions in Yunnan

There is, reportedly, one academic article in print (and on J-Stor) by
an American academc on "Sanskrit sources in Yunnan" --I must find a
copy somehow, but I do not even know the author's name.

I have, thus far, found only the following (salient but not quite the
article described to me):

The Dharani Pillar of Kunming, Yunnan. A Legacy of Esoteric Buddhism
and Burial Rites of the Bai People in the Kingdom of Dali (937-1253)
Angela F. Howard
Artibus Asiae, Vol. 57, No. 1/2 (1997), pp. 33-72
doi:10.2307/3249951
This article consists of 40 page(s).
