These were growing (primarily in sand by a lake) in SE British Columbia at an elevation of around 3000 feet. I'm not sure what they are and would love any help if possible. I initially thought it might be creamy peavine, but now I think it may be yellow hedysarum, American milk-vetch, or Canada milk-vetch? http://youtu.be/oVwOXBWv_TY Thanks in advance for any help!
