Identity HelpUnknown #1 - Point of Rocks, New Mexico

Could this actually just be pectolite, albeit unusual morphology for pectolite?

I never saw in hands any sample from Point of Rocks, but in Khibina pectolite very often is altered with formation of earthy reddish-brown mixture of Mn and Fe oxides. Cavities in this sample http://www.mindat.org/photo-72661.html are after elimination of such secondary products. And reddish coloration of feldspar is caused by inclusions of such altered pectolite.
Alteration (not so deep as in Khibina) with darkening also is very typical for pectolites from Dara-i-Pioz massif.
