Looking for detailed Topo St. Helens Worm Flows

Looking for a detailed topo map (electronic) of St. Helens Worm Flows route for May 22nd trip. Have seen lots of people up there in May in the past, but not many TRs lately.

Thanks

Look at the ones available through National Geographic's products. They have various software packages that include the map. Depending on the software package you can get all the maps for Washington or just the quads you are interested in. The Weekend Explorer-Seattle won't have what you are looking for. They'll also talk nicely to GPS units. I have both the TOPO explorer and topo washington versions and the maps are basically electronic USGS maps. My GPS has Garmins map card in it and it lines up right with the topo data.

mapper.acme.com ?

GPSVisualizer, map of St Helens

there is even a tool to create waypoints and tracks to upload to your GPS, free utility...

I think if I was going to purchase a full software package I would pick Topofusion over the NG products. More features and covers all of N America (instead of individual states)

I've got a paper copy of pre-eruption I could scan

Great suggestions, thanks.
