Spent the last weekend of March 2011 at Timberline Four Seasons Resort. The conditions were fantastic. A large percentage of trails were open. Temps all weekend hovered near freezing. The top of the mountain stayed solid all weekend. The bottom got a slight bit soft on Saturday afternoon with the sun coming out. On Sunday, we woke up to two inches of new powder and had a couple of excellent runs down the moutain. Fortunately, they had groomed out the moguls from Off The Wall which left an incredible, steep trail that I hadn't gone on before. I hope they groom it in the future as it really was a great trail. White Lightning was it's classic awesomeness--allowing nice wide GS-style turns all the way down. We scheduled this weekend months ago, expecting slushy conditions but really lucked out. I'm sure the resort could stay open at least one more weekend but it's tough getting people to come out that far. Great ski/board trails at this resort. Definitely worth the long drive for a weekend stay.
