Hey all, Just wondering if anyone can help with two flower id's here. I don't have my good idetification book at home right now. The picture was taken in eastern British Columbia at an elevation of around 2675m (8775 ft). The yellow flowers are around a cm^2 in size and that provides a frame of reference for the size of the white flowers. I'm thinking the yellow ones may be Draba paysonii aka yellow draba aka yellow whitlow-grass? The only guesses I'd have on the white ones would be a stunted specimen of silver rockcress or rock jasmine? Sorry, the picture gives no help with the stem/leaves of the white flowers. Any help appreciated. Many thanks in advance!
