Hey, Are you the 50 something year old woman who took up snowboarding for the first time last year? GREAT progress
Don't give up. Good technique takes you everywhere. You can absolutely carve a snowboard on steep icy slopes (pencil line, linked c-shape turns, speed controlled to desired levels)
Just edited this post for the zilionth time.
--> Listen to snowwolf. Despite having knowledge, conveying concepts to a student is extremely hard. Snowwolf is very good at this. He will probably not give you incorrect information either. Something I've seen while reading through these responses...
Ice is a GREAT opportunity to hone technique/stance setup. I love ice!!!
