another mass distribution to account for the gravity anomalies for Hawaii. In 

 this case there were considerably more gravity data available. Fig. 23 shows 

 the resulting section. The asymmetry indicated in the section would be more 

 exaggerated if the section were made farther to the southeast and less exag- 

 gerated if it were made farther to the northwest. 



A continuous gravity profile has been obtained on an east to west crossing
