For over 40 years The amphibole from here has been called "actinolite", much of it green and some near colourless. It is probably Tremolite Actinolite series, but analysis is required to sort them. Please see: http://www.mindat.org/forum.php?read,106,239673,23987
EDS was done on a typical sample in 2016 and showed insufficient iron to be actinolite. It is therefore very likely that all the "actinolite" from there is tremolite.
