Change individual cell values in a DEM

I want to edit a DEM and manually select certain grid cells and change their value. And I want to change the value to particular numbers so would need to do this manually also.

Any ideas on how to do this in ArcGIS?

A few ways to do it.
- Use the CON tool in Spatial Analyst
- use RasterToPoint, edit the values in the feature class and then do PointToRaster (remember to set the cell size and extent to that of your original raster)
- RasterToASCII, edit the text file, ASCIIToRaster

Thanks. I was sort of hoping that Arc would by now allow you to select a cell, change the pixel value, and save. And not have to create an interim layer or dataset. I have certain locations where I want to extrude the cell to a certain height in the DEM.
