Sorry, I over simplified.. it took me a few gos to get what I wanted (you'll find a thread on this somewhere on this reflector)
Go to the summits database.. http://www.sotadata.org.uk/summits.aspx
Download the list of all summits.. push into a spreadsheet
I used column headings.. "name,full desc,color,symbol,alt (feet),latitude,longitude, date, points, desc"
Complete the field updates per your logs.
Save as a CSV file
