Aside from a small amount of snow/ice left above 7,000 feet when I was there in late February, the road to Mahogany Flat seemed to be very much in passenger car condition. I agree with MoapaPk that the likelihood of much erosion damage is low this spring. I wouldn't be surprised if the road has been snow free since I was there. Although snow is possible today, it is likely that no precipation has fallen the past three weeks. If going in the summer, I suppose thunderstorms could cause the road to roughen. We actually had rare significant thunderstorms on the coast last night and in the central valley the past couple of days.
As far as anyone interested in the hike, about a week ago snow was visible on Telescope, but from a distance, Rogers, Bennett, and most of the approach looked snow-free. I also saw the recent trip report from late March and looked back at some of my own pictures from late February. I suspect snow and mud can now be avoided (especially if willing to leave the main trail) with the exception of hiking the final ridge/switchbacks to Telescope peak (ridge would be more advisable in slick conditions). Barring much new accumulation, I suspect the small amount of snow that is left won't last long this time of year.
