The ground temperature at 5 feet below the surface is typically more stable and closer to the average annual air temperature of the region.
The ground temperature at 10 feet below the surface is typically around 50-60 degrees Fahrenheit.
The ground temperature at 20 feet below the surface is typically around 50-60 degrees Fahrenheit.
The ground temperature at 20 feet below ground level typically remains stable and ranges between 50-60 degrees Fahrenheit. This is due to the Earth's natural insulation properties that moderate temperature fluctuations at deeper levels.
The temperature at 25,000 feet would be 12 degrees. This can be calculated by taking the ground temperature of 62 degrees and subtracting 2 degrees for every 1,000 feet (25,000 feet ÷ 1,000 feet = 25; 25 x 2 degrees = 50 degrees; 62 degrees - 50 degrees = 12 degrees).

Based on your question alone, it is impossible to tell how many millennia it would take for an object "like this" to be buried 300 feet in the ground. We cannot see the object to which you are referring.
300' x 300' = 90,000 square feet
It should not be stuck in well. If you are 300 feet, it is going to take a lot of pull to get it out. You might just think it is stuck?
300 feet.
On average, the temperature decreases by around 3.5°F for every 1,000 feet increase in elevation, known as the lapse rate. At 8,000 feet altitude, you can expect the temperature to be around 28°F cooler than at ground level, so it would be approximately 42°F at that height if the ground temperature is 70°F.
