GPS Elevation Data, Waypoints, and Tracks

In theory anyway, elevation can be calculated from GPS data. Surveying
is done this way as I understand it.

Can any of the Garmin devices record a waypoint with calculated
elevation? I have a nuvi 350 and it only seems to know about the topo data.

Can any of the Garmin devices record a track, say, every 20 feet or
whatever that includes calculated elevation data?

I apologize for my ignorance and thank you for any help.

One other point: my nuvi 350 calculates elevation and it can be seen on
the Satellite panel (click the Signal Strength bars on the main menu). I
don't see this data anywhere else in the unit.

Yes. All the Garmin receivers that I have used record the track with
altitude. In the eMap, GPS V, Street Pilot III and 2610 this is GPS
altitude, ie determined by measurement from GPS satellite signals. I think
this is what you mean by calculated. In the eTrex Vista C and GPSMap 60CSx
the altitude is determined by the built-in barometric altimeter. Most of
them have a setting to determine how often (in time or distance) a track
point is recorded, but I usually just leave it on automatic. The 60CSx can
be set to record onto the microSD data card, so it can hold many days
tracks. The StreetPilots struggle to hold one.

FYI, Garmin nuvis don't record tracks. The new 700 series will.

Will an eTrex H or Legend record the track with altitude?
