Strange fern, found around 6000ft among some rocks littered with Kruckerberg's sword fern. Interesting geology in this area, lots of ultramafic, limestone and even some serpentine slivers: http://www.geosciencebc.com/i/pdf/2006-005-FinalReport.pdf.

Honestly looks like Adiantum capillus-veneris
to me but this seems preposterous given it is only known from two disjunct localities in B.C..
